Researchers Raised Concern On Plastic Chemical BPA

Sunday, January 19th, 2014

Evidences revealed that exposure of the womb to plastic chemicals can potentially increase prostate cancer, according to studies. Chemicals found in water bottles, soup cans, and paper receipts can also increase prostate cancer. The development of human prostate cells is studied in mice and the study yielded evidence that when mice are fed with bisphenol A (BPA), the risk of developing cancer or pre-cancerous changes is three times higher. BPA us a plastic chemical, which is used to soften plastic, is feared by researchers due to its ability to mimic estrogen. In the study, the doses of BPA received by the mice are somewhat the same as those seen in pregnant women.

The new study of laboratory rats suggests that prostate cancer, which usually strikes men over 50, may develop when BPA and other estrogen-like, man-made chemicals pass through a pregnant woman’s womb and alter the genes of a growing prostate in the fetus. Prostate cancer develops in one in every six men but the progression increased over the last 30 years. Researchers exposed newborn rats to low doses of BPA and found the structure of genes in their prostate cells was permanently altered, a process of reprogramming in early life that promotes cancer in adulthood.

When they are fetuses, the prostate gland is remarkably sensitive to natural estrogen. This study resulted to researchers to long speculate that exposure to estrogen-like chemical in the womb may have contributed to the increasing number of prostate cancer in men. BPA possesses a characteristic that triggers changes in the genes that are passed on to the next generation, which is different from carcinogen chemicals.

Men with prostate cancer have found refuge in robot-assisted prostatectomy because it renders minor post-operative complications and rapid recovery after the surgery. A research was made to look into the robotic prostate surgery and it was found out that 117 prostate cancer men has short stay in the hospital and were able to bounce back with their normal physical activities, including sexual intercourse. Da Vinci surgical robot has been a heated debate among health experts whether it offers additional benefits over traditional minimally invasive surgeries.






MRI Test For Prostate Cancer

Sunday, January 19th, 2014

Prostate cancer is one of the most common cancers in men. Men can encounter a few health issues of the prostate gland as they grow older. Infection and tumors can develop in the prostate gland. Annual prostate test is recommended to men who are aged 50 and above. Although the tumors that develop on the prostate gland are non-cancerous, these tumors seldom turn out to be cancerous.

Magnetic resonance imaging (MRI) is a non-invasive medical test that helps physician diagnose and treat medical conditions. It is a form of medical imaging that measures the response of the atomic nuclei of body tissues to high-frequency radio waves when placed in a strong magnetic field, and that produces images of the internal organs. The images can then be examined on a computer monitor, transmitted electronically, printed or copied to a CD.

The MRI of the prostate gland may be prescribed by the physician for a number of reasons:


1. To distinctly view the magnitude of prostate cancer (particularly to view if the cancer is within the prostate gland or if it has spread outside the gland).

2. It is one way of showing any indication of prostate cancer or if the level of prostate-specific antigen (PSA) is high. The prostate gland produces PSA, which can be determined in a blood sample. PSA is commonly high if a person has prostate cancer; however, it can be high for some reasons, such as infection of the prostate gland known as prostatis.

3. Radiotherapy treatment can be easily planned with the help of an MRI.

4. It helps check if cancer has developed again after treatment.


The doctor can often tell from looking at any tumors found what type of cancer it is likely to be, allowing them to determine the best treatment options much more easily. The more information the doctor has about the cancer, the more effective the treatment is.

Robot-assisted surgery is now the most popular laparoscopic procedure and treatment for prostate cancer, offering lesser complications and faster recovery after prostatectomy. Researchers discovered that 171 men facing prostate cancer surgery, who are having robotic surgery are expected a short stay in the hospital and able to resume with their normal physical activities, including sexual intercourse. Not only does robotic surgery is popular to patients but it has also gained recognition in urologic surgery because it saves kidney function. However, there are people who believe that the benefits may not seem realistic.





Dangers Associated With Gallbladder Removal

Sunday, January 19th, 2014

Gallbladder is a hollow organ that is located just under the liver. Gallbladder removal surgery has been conducted in over 12 million individuals every year, medical journals disclosed. The need for gallbladder removal may sometimes be imperative; but not always. The symptoms of gallstones may be experienced by some individuals while others go on with their lives never experiencing the dreaded symptoms. Stress and eating wrong foods can contribute to increasing pain caused by gallstones. In this case, you may need to go under the knife to remove the gallstones.

The surgery aims to remove the gallstones and inhibit potential development of gallbladder cancer. Although the removal of the gallbladder is relatively quick and safe procedure, like all surgical procedure, there is a small risk of complications.


  • Infection. The risk of infection may be experienced in almost one in 15 gallbladder removal surgery. The use of antibiotics can treat infection in patients.
  • Leak of bile from the bile duct. The risk of bile leaking from the bile duct occurs in one in 100 cases. The tube that connects the gallbladder to the main duct is clinched by special clips.
  • Bleeding. After gallbladder removal, there is a two percent risk of bleeding. Anti-clotting drugs and cholangitis can increase the risk of bleeding.
  • Acute cholecystitis (inflammation of the gallbladder). This condition occurs when the stone gets stuck in the outlet of the gallbladder and does not release. First there is a chemical reaction of the bile literally starting to digest the gallbladder causing inflammation and unremitting pain. Bacteria can easily penetrate in gallbladder, which may result to gangrene of the gallbladder.


Robot-assisted surgery is now the most popular laparascopic procedure and treatment for gallbladder stones and cancer, offering lesser complications and faster recovery after prostatectomy. High school students were given a chance to test drive and view robotic surgery performed by a trained surgeon.





Lung Cancer Screening Important For Smoker, But Not All

Tuesday, January 14th, 2014

Lung cancer causes more deaths than breast, colon, and prostate cancer combined. Lung cancer is often detected through screenings and treated surgically, such as the robotic surgery. However, problems often occur because patients are unaware of the potential risks caused by robotic surgery.

There are specific current or former heavy smokers who may be required for lung cancer screening yearly to help reduce the risk of death caused by lung cancer, the leading cause of cancer death all over the world, says the government. People who smoked an average of one pack of cigarettes daily for 30 years or an equivalent amount, such as two packs a day for 15 years, are those must undergo CT scans.

Approximately, there are 10 million people in the world who smoke but not all of them are qualified for screening. Screening may be unsuitable even for high risk patients who are not able to bear cancer treatments or if they kicked the habit more than 15 years ago. There are about 160,000 people in America who die every year from lung cancer. A person who smokes has higher chance of lung cancer and it goes even higher the more and longer he/she smokes. Treatment for lung cancer is usually late because of late diagnosis but until now, there is no good means of early detection.

CT scans pose some risk from radiation exposure. The amount of exposure in a low-dose spiral CT is about the same as in a mammogram. Also, there is the risk of “false positives,” when the CT finds something abnormal that turns out not to be cancer. These findings must be followed up with more CT scans and sometimes with a lung biopsy or chest surgery, which can pose additional risks and a lot of worry. This year alone, it is expected that over 160,000 people will die of lung cancer in the United States.


Bilateral Oophorectomy Outweighs Risks

Tuesday, December 31st, 2013

Women undergo hysterectomy with bilateral oophorectomy (removal of the ovaries) to prevent the development of ovarian cancer. Each year, hysterectomy is performed 300,000 times or 55 percent of the population of women in the United States. Still, there are dangerous effects caused by the removal of the ovaries. Bilateral oophorectomy increases the risk of diabetes and other chronic diseases. Women need to plan and consider carefully oophorectomy if they have low risk for ovarian or breast cancer.

The researchers found that, over 28 years of follow-up, 16.8 percent of women with hysterectomy and bilateral oophorectomy died from all causes, compared with 13.3 percent of women who had ovarian conservation. Women with ovarian risk who underwent oophorectomy have lower risk of death (four women with oophorectomy versus 44 women with ovarian conservation). Before the age 47.5 years, oophorectomy was tied to a lower risk of death from only breast cancer. The risk of death is high if the women did not use estrogen therapy and had bilateral oophorectomy.

A woman can have a sharp decline in circulating ovarian estrogen and androgens in premenopausal oophorectomy. A woman may suffer from coronary heart disease, hip fracture and neurological conditions if her estrogen level declines. There are 350,000 women who die from coronary artery disease compared to 15,000 American women who died from ovarian cancer. Hence, the risk coronary artery disease and neurologic conditions exceeds the benefits of oophorectomy of reducing the risk of ovarian cancer.


Small instruments are secured in the robotic arms and the surgeon sits at a console a few feet away and gets three dimensional real time views of the surgery from start to end. Places in Europe and United States have been using robotic surgery. One of the advantages of robotic hysterectomy is that it benefits women to enjoy sex better after the surgery. The FDA has recommended patients that before deciding to undergo a robotic surgery, they need to talk to their respective doctors in order to determine if da Vinci is the best surgical procedure for them.



Who Are At Risk Of Lung Cancer

Sunday, December 15th, 2013

Lung cancer is a killer cancer in the United States, which affects both men and women. There are more death caused by lung cancer compared to other type of cancers combined. There are more than 6,800 men and over 6,600 women suffered from lung cancer every year and unfortunately, approximately 4,800 men and over 4,300 women die from this debilitating condition. Anyhow, patients with lung cancer can be effectively treated with robotic surgery. Robotic-assisted procedures have been launched by some hospitals to treat various conditions, including lung cancer.

In order to avoid lung cancer, people should be familiar with the potential risk factors that increase the development of lung cancer. There are a number of risk factors that may increase the potential of a patients to develop lung cancer. There are risk factors for lung cancer that can be prevented while there are some that cannot be controlled, say researchers.

Lung cancer can develop with these risk factors.

Smoking: A person who heavily smoke cigarettes has high risk of lung cancer. There is a 90 percent risk of lung cancer in a smoker. One cigarette stick has reported more than 7000 chemicals. Lung cancers increases with the number of cigarette consumed every day and the number of years you smoked.

Secondhand Smoke: Secondhand smoke when inhaled can boost your risk for lung cancer, despite not smoking cigarette. Secondhand smoke contains the same chemical as smoke that is actively inhaled.

Family History: The risk of lung cancer increases when a member of the family who had been diagnosed with lung cancer.

Exposure to Radon Gas: Exposure to radon gas has been estimated to be the second leading cause of lung cancer in the United States. The risk of lung cancer from radon exposure is higher in people who smoke.

Asbestos: High levels of asbestos in workplace increase the potential of a worker for lung cancer. Worker who smoke and are exposed to radon gas have much higher risk of lung cancer.

Excessive alcohol use: Lung cancer may occur in people drinking alcohol more than the moderate amount — no more than one drink a day for women or two drinks a day for men.

Poor Diet: More research is needed to clarify the role that diet plays in lung cancer risk. However, there are studies claiming that eating vegetables and fruit may help lower the risk of lung cancer. Some studies have shown a reduced risk of lung cancer with a high intake of selenium.


Ethnicity: An Independent Impact In Hysterectomy

Wednesday, December 11th, 2013

Black, Hispanic and Asian women are found to be fifty percent less to undergo hysterectomy, according to a research. The variation of patient, financial, and hospital characteristics is reserved for the findings. Demographic factors (age, race/ethnicity, insurance); patient factors (cancer diagnosis, fibroids, endometriosis, prolapse, menstrual disorders, age, severity of comorbidities, obesity); and hospital factors (urban/rural, teaching status, size, and region of country are controlled multivariate regressions analysis.

A probe was conducted among Hispanic women due to lack in information on this account, which is the outcome of the absence of accurate information on the ethnicity in national surveys, and because other data imply to under-use medical services among Hispanic women.

The information based on the respondents’ self-supported history of hysterectomy and identification with any of a variety of Hispanic subgroups. The researchers conducted a probe in determining the women’s level of acculturation to establish whether the interview was done in Spanish, English or a combination of the two. An analysis on the women’s acculturation has been examined by the researchers whether the interview was conducted in Spanish, English or a combination of the two. They also classified women into three groups: born on foreign soil and living in the United States for fewer than 10 years, born on foreign soil and living in the United States for 10 years or more, and born in the United States.

Moreover, the research led to the finding of the following: Hispanic women had less education and lower incomes than white women–all factors with significant effects on hysterectomy rates–it is uncertain how much ethnicity alone accounts for the differences they found. It may possible that there is an independent link between the level of acculturation and hysterectomy. Although hysterectomy is used to cure gynecological conditions that are commonly not life-threatening, researchers observed that white women overly used the procedure while it is rarely used by Hispanic women.

Before undergoing a any type hysterectomy including robotic surgery, FDA tells patients to talk to their respective doctor in order to determine if da Vinci is the best surgical procedure for them. Some patients experienced problems in robotic gynecological surgeries that lead to filing of lawsuit against surgeons.




Patients Beware Of Inflammatory Bowel Disease

Saturday, December 7th, 2013

Today, there are millions of people who are suffering from digestive problems in the United States. Inflammatory bowel diseases (IBD) is a prevalent digestive ailment in which chronic inflammation occurs in all or part of the digestive tract. IBD is most common in individuals aged between 15 and 35 although it often occur in children as young as 18 months, medical journal says. The factors increasing the risk of IBD still remains unknown. The cause of IBD may have a connection to the combination of genetic and non-genetic factors, such as environmental factors that interacts with the body’s immune system.

Symptoms can range from mild to severe. However, it is likely for a symptoms to come and go , sometimes going away for months or even years at a time. When people with IBD start to have symptoms again, they are said to be having a relapse or flare-up. There are two kinds of IBD, the ulcerative colitis and the Crohn’s disease. These diseases can have be painful and debilitating, and it has a potential to be life-threatening.

In ulcerative colitis, the top layer of the large intestine is affected. The disease causes swelling and tiny open sores, or ulcers, to form on the surface of the lining. Pus is produced due to the bleeding of the ulcers. The person’s intestinal wall may diminished in severe cases of ulcerative colitis. The leakage may cause the spilling of the contents of the large intestine, including bacteria, into the abdominal cavity or leak into the blood. This causes a serious infection and requires emergency surgery.
Crohn’s disease can affect all layers of the intestinal wall. Areas of the intestines most often affected are the last part of the small intestine, called the ileum, and the first part of the large intestine. But Crohn’s disease can affect any part of the digestive tract, from the mouth to the anus.
You are a candidate to undergo minimally invasive surgical option known as da Vinci surgery if your surgeon recommends surgery for inflammatory bowel disease. A surgical robotic system is used during da Vinci surgery. Howbeit, there are some who questioned the benefits of robotic surgery over traditional laparascopic surgery. The FDA has recommended patients that before deciding to undergo a robotic surgery, they need to talk to their respective doctors in order to determine if da Vinci is the best surgical procedure for them.


A Comparison On Colorectal Cancer Treatments

Friday, December 6th, 2013

The colon and rectum composed the large bowel. In case of colorectal cancer, adenomatous polyps may begin to form on the inner wall of the large intestine. Colorectal cancer may occur when the number of these polyps increased. Researchers are still studying the exact factors that trigger colorectal cancer. Approximately 150,000 individual are affected with colorectal cancer every year, thus making it the third most common cancer in both men and women, statistics say.

Colorectal cancer is most often treated with surgery to remove the tumor, and possibly, chemotherapy and radiation.

  • Chemotherapy. Chemotherapy uses chemical to treat colorectal cancer. This type of treatment specifically means to destroy the cancer cells. The use of antibiotics or other medications may be used by chemotherapy to treat any illness or infection. Moreover, before you decide, you need to know that there are several disadvantages that are associated with chemotherapy.
  • Radiation therapy. Radiation therapy is a cancer treatment. It uses high doses of radiation to kill cancer cells and stop them from spreading. The radiation may be external, from special machines, or internal, from radioactive substances that a doctor places inside your body. However, the disadvantage of receiving radiation therapy is that healthy cells can be also destroyed.
  • Surgery. Surgery is usually the main treatment for bowel cancer, but in about one in five cases, the cancer is too advanced to be removed by surgery. Chemotherapy, radiotherapy or biological therapy is also required although you already have surgery.

If your doctor recommends colorectal surgery, you may be a candidate for minimally invasive da Vinci surgery. This procedure uses a robotic surgical system.
Just like any other forms of surgery, the benefits may depend on the patient and procedure. Colon cancer patients may not be appropriate to undergo robotic surgery although it is believed to be safe and effective. Serious health complications are believed to be caused by robotic surgery but its manufacturer denied these allegations. The FDA has recommended patients that before deciding to undergo a robotic surgery, they need to talk to their respective doctors in order to determine if da Vinci is the best surgical procedure for them.


Patient’s Guide To Heart Surgery Recovery

Saturday, November 30th, 2013

Coronary heart diseases are regarded to be the biggest killer of people. The symptom of coronary heart disease can be control and the risk of further complications can be reduced through treatment, although it is not curable. A bypass surgery is recommended by the doctor if you are suffering from coronary heart disease or angina to help improve the blood supply to your heart muscles. The benefits of a bypass surgery are to ease the symptoms and improve one’s quality of life.

The patient’s response to a surgery may differ from other patients. And recovery from each specific surgical procedure, whether coronary artery bypass for clogged arteries or a valve repair/replacement for a narrow or leaky valve, is somewhat different as well.

A set of instruction is given to a patient, before leaving the hospital following heart surgery, for self-care during the first phase of recovery which lasts about six to eight weeks. The first week after the coronary surgery, the nursing staff in the hospital met all your postoperative requirements. Your obligation when you arrive home is to care for your self. You need to always think that you are responsible for your healing. You should always think that you cannot expect anyone to help you take the responsibility but yourself.

Self-care is considered to be an essential part of life and it is also about being responsible for your own health and well-being with the support of those involves in your care. It involves actions of taking care for yourself every day in order to be fit and maintain good physical and mental health, prevent illness or accidents, and care more effectively for minor ailments and long-term conditions.

There is one minimally surgical treatment, called robotic surgery, that is used by a number of patients. But there are allegations that the maker of device used in robotic surgery has failed to notify the public of its product dangerous side effects. Health experts questioned the expensive price of undergoing robotic surgery. The FDA has recommended patients that before deciding to undergo a robotic surgery, they need to talk to their respective doctors in order to determine if da Vinci is the best surgical procedure for them.
