For breast cancer patients, there are three common surgical interventions: bilateral mastectomy (the removal of both breasts), unilateral mastectomy (the removal of the affected breast), and lumpectomy (the selective removal of cancerous tissue within the breast) plus radiation. 


It has generally been believed that more attractive men had better semen quality.


Visible blood in urine is the best known indicator of bladder cancer but new research  finds that invisible blood in urine may be an early warning sign of bladder cancer. 

Scientists at the University of Exeter Medical School found that 1 in 60 people over the age of 60 who had invisible blood in their urine transpired to have bladder cancer. Thay's about half those who had visible blood in their urine but higher than figures for other potential symptoms of bladder cancer that warrant further investigation. 


In a cell's nucleus, chromosomal DNA is tightly bound to structural proteins known as histones, an amalgam biologists call chromatin.

Until a few decades ago, histones were regarded as a nuclear "sidekick," the packing material around which the glamorous DNA strands were wrapped. 


Epidemiologists have correlated eating over 10 portions per week of tomatoes with an 18 percent lower risk of developing prostate cancer, new research suggests.

Prostate cancer is the second most common cancer in men worldwide and diagnosed rates are higher in developed countries, which some claim means is due to a Westernized diet and lifestyle.

To assess if following dietary and lifestyle recommendations reduces risk of prostate cancer, scholars at the Universities of Bristol, Cambridge and Oxford looked at the diets and lifestyle of 1,806 men aged between 50 and 69 with prostate cancer and compared with 12,005 cancer-free men.




Cancer is the blanket term for over a hundred diseases where abnormal cells divide and invade tissues through blood and lymph systems. The extra cells are often detected in the form of a tumor that people notice as their first symptom, and those can be benign or malignant.

It's a trick almost everyone knows: to open a locked door, slide a credit card over the latch.

Scientists at The Scripps Research Institute (TSRI) used a similar strategy when they attempted to disrupt the function of MYC, a cancer regulator thought to be "undruggable." The researchers found that a credit card-like molecule they developed somehow moves in and disrupts the critical interactions between MYC and its binding partner.

MYC is a transcriptional factor, meaning it controls gene expression. When MYC is overexpressed or amplified, the unregulated expression of genes involved in cell proliferation, a key step in cancer growth, follows. MYC is involved in a majority of cancers, including Burkitt's lymphoma, a fast-growing cancer that tends to strike children.


Obstructive sleep apnea, in which people stop breathing for short periods while sleeping. Breathing pauses last from seconds to minutes and may occur 30 times per hour, after which normal breathing then starts again, often with a snoring or choking sound.

About five percent of adults have some form of sleep apnea. It can ncrease the risk of high blood pressure, heart attack and arrhythmias. It is most prevalent in obese people and some studies have also postulated that obstructive sleep apnea may be linked to cancer because of low levels of oxygen in the blood. 


Mutations in a gene named
CTR9 gene
that helps regulate when genes are switched on and off in cells have been found to cause rare cases of Wilms tumor, the most common kidney cancer occurring in children.


Since President Richard Nixon declared a War on Cancer over 40 years ago, survival rates have improved dramatically and cancer rates have even gone down, despite claims that everything from DDT to nuclear energy to genetically modified foods would cause a cancer epidemic.

Yet not all cancer survival has improved. Pancreatic cancer still has  the lowest survival rate of the 21 most common cancers, and in 40 years just over 3 percent of pancreatic cancer patients survive for at least five years, only a fraction more than the 2 percent who survived that long in the early 1970s.
