Hormonal Therapy May Reduce the Risk of Colo-Rectal Cancer

Recent studies show that hormonal replacement therapy, which was abandoned by the women in the age finding that could lead to breast cancer, reduces substantially the risk of a colo-rectal cancer. The most remarkable reduction in the risk-48 percent-was observed in women who received hormonal therapy with combined estrogen and progestin for a period of 2 to 5 years, researchers reported in the...

Cancer FAQ

Q: What is Cancer? A: Cancer is a large group of diseases characterised by an uncontrolled growth of abnormal cells. Q: What Causes Cancer? A: To date, the exact cause for cancer in many patients is still unclear. But several factors have been identified as cancer causing. These include smoking, high-fat diet, alcoholism, exposure to substances like fluorocarbons and asbestos, ionising radiation...

Prostate Cancer Treatment Risk

An increasingly popular prostate cancer treatment also makes bones brittle and may be responsible for over 3,000 fractures each year in the United States, researchers reported recently. The treatment calls for blocking the effects of the male hormone testosterone, either with drugs or by castration. Until now, doctors have regarded the treatment as relatively harmless, Vahakn Shahinian, chief...

Understanding Lung Cancer and Treatment Breakthroughs

November 28 2005 Monday Lung cancer develops when toxic substances such as tobacco smoke damage lung cells. The cells lose their ability to regulate growth, so they divide and multiply at an abnormal rate. In time, a mass of cells called a tumour develops. When this tumour turns malignant or cancerous, it starts to invade and destroys surrounding tissue. Generally, cancers that develop in...

Spot Stomach Cancer Early With This Device

Researchers here have pioneered a special endoscope that they hope will help reduce the high mortality rate for stomach cancer. The endoscope - a flexible, thin tube used to look inside the body - allows doctors to examine the stomach lining in microscopic detail for abnormal cells that sound the alarm on cancer. 'It allows us a clear view of every part of the stomach and increases the odds of...

Frying Foods Boost Up Cancer Risk

Women who eat crisps, chips or other fried foods like roast every day may double their chances of ovarian or womb cancer, say scientists. Dutch researchers made a survey of 120,000 people on their eating habits, and found that women who ate more burned appeared more at risk. Analysis of these findings suggested that those who ate 40 micrograms of acrylamide a day - equivalent to half a pack of...

Know Cancer to Fight It

The Facts Normal cells have a life cycle in which they grow and replace themselves in a controlled manner. When cells start to grow abnormally and uncontrollably, cancer develops. Unlike normal cells, cancer cells do not die and replace themselves. They continue to grow and multiply as abnormal cells, quickly forming a mass of tissue called a tumour. Cancer cells may travel to various parts of...

Current Trends in the Treatment of Lymphoma

The potentially curable nature of lymphoma, often even in advanced stages, sets this malignancy apart from many others. However, a significant number of patients will suffer a relapse following successful initial treatment. Of these patients, many will respond well to further treatment to salvage a cure. Unfortunately, many others will perish from the disease. The fight to discover better...

Mathematical Models Aid - The Understanding of Cancer

Practitioners of so-called hard sciences-those backed up by the math-ematical rigour of formulae and equations-have traditionally looked down on the squishy end of research. That disdain has evaporated a bit over recent years, as government money has migrated from physics to biology and medicine. But it is disappearing as biologists show that they can be just as quantitative as their hardedged...

Thermal treatments of cancer are remarkably effective

Even as some scientists are seeking to understand how cancer works, in order to treat it more effectively, others prefer a more robust approach. They are exploring ways of killing cancer cells by heating them up without damaging surrounding healthy tissue. Although various such treatments have been tried in the past, advances in medicalimaging technology (which allow surgeons to see inside a body...

Mesothelioma

Mesothelioma is one of the most deadly forms of cancer known today - an incurable disease that claims the lives of over 10,000 victims in the United States each year. While medical science continues to develop miraculous technology that prolongs many of the lives ravaged by this insidious condition, a cure is still out of reach and the prognosis is always fatal. Tragically, there is usually...

How to Prevent Cancer

Globally, cancer is a growing problem. From 2000-2005 a significant rise in the number of cases is anticipated worldwide. At present, from a world population of 6 billion about 10 million cases are diagnosed annually with 6 million deaths. However, 50 per cent will occur in developing countries, which have 5 per cent of the resources to treat it. This figure will rise to 20 million by 2020 from a...

Answers to Cancer

In the study of cancer, never have the concomitant factors that can transform a healthy cell into a malignant cell been so well understood as they are today; for this, we have mainly molecular biology, genomics and post-genomics to thank. Today we are at last beginning to understand the underlying mechanisms by which cancer develops. This scientific and medical progress has led to changes in our...
