Colon Cancer

Every year, about one million new cases of colon cancer are diagnosed worldwide. About 150,000 new cases are detected each year in the United States. Over a lifetime, about 1 in 19 people develop colon cancer and nearly 50,000 people are expected to die from it in the U.S. this year.

What Causes Colorectal Cancer?

Cancer occurs when a normal cell divides and multiples uncontrollably. Normally cells are regulated in their growth, maturity, division and death by the DNA present in their nucleus. With damage to the DNA the cells may become rogue and multiply uncontrollably to give rise to tumors.

Study links pregnancy specific genes to poorer lung cancer outcomes in women

Lung cancer can co-opt genes that normally help a fetus develop and evade the mother's immune system. And while these pregnancy-specific glycoproteins (PSGs) can get activated in the cancers of both men and women, female patients had poorer outcomes, a Memorial Sloan Kettering Cancer Center (MSK) research team has found.
