Cancer begins in your cells, which are the building blocks of your body. Normally, your body forms new cells as you need them, replacing old cells that die. Sometimes this process goes wrong. New cells grow even when you don't need them, and old cells don't die when they should. These extra cells can form a mass called a tumor. Tumors can be benign or malignant. Benign tumors aren't cancer while malignant ones are. Cells from malignant tumors can invade nearby tissues. They can also break away and spread to other parts of the body.

Most cancers are named for where they start. For example, lung cancer starts in the lung, and breast cancer starts in the breast. The spread of cancer from one part of the body to another is called metastasis. Symptoms and treatment depend on the cancer type and how advanced it is. Treatment plans may include surgery, radiation and/or chemotherapy.

Bioactive compound from neem plant shows promising effects on prostate cancer

A team of international researchers led by Associate Professor Gautam Sethi from the Department of Pharmacology at the Yong Loo Lin School of Medicine at the National University of Singapore has found that nimbolide, a bioactive terpenoid compound derived from Azadirachta indica or more commonly known as the neem plant, could reduce the size of prostate tumour by up to 70 per cent and suppress its spread or metastasis by half.

T-Bear brings hope to kids diagnosed with cancer at Seattle Children's Hospital

T-Bear brings hope to kids diagnosed with cancer at Seattle Children's Hospital

He may not be able to fly, or be as fast as the speed of light, but for children who have been diagnosed with cancer at Seattle Children's, the cuddly teddy bear who wears a mask and purple cape is still a super hero to them - he gives them strength. [More]
Tumor Paint lights the way for surgeons during brain surgery

Tumor Paint lights the way for surgeons during brain surgery

In December of last year, Laura Coffman began to notice that something wasn't quite right with her 2-year-old son, Hunter. He was leaning to one side and seemed to lose his balance easily. When he became lethargic and started vomiting a few days later on Dec. 28, she knew it was time to see the pediatrician. [More]

Rehabilitation programme for heart disease could help bowel cancer patients

Rehabilitation programme for heart disease could help bowel cancer patients

Could rehabilitation programmes for heart disease patients be used to help people recovering from bowel cancer get back on their feet? That's the question cancer care experts at the University of Stirling have been exploring. [More]
Scientists discover new switch that coordinates DNA repair and cell death

Scientists discover new switch that coordinates DNA repair and cell death

The genetic information of every cell is encoded in the sequence of the DNA double helix. Double strand breaks in the DNA, which can be induced by radiation, are a dangerous threat to the cells, and if not properly repaired can lead to cancer. [More]
