Oral cancer is cancer that develops in the tissues of the mouth or throat. It belongs to a larger group of cancers called head and neck cancers. Most develop in the squamous cells found in your mouth, tongue, and lips.

A man's prostate produces the seminal fluid that nourishes and transports sperm. Symptoms include difficulty with urination, but sometimes there are no symptoms at all.

Two major types of lung cancer are non-small cell lung cancer and small cell lung cancer. Causes of lung cancer include smoking, second-hand smoke, exposure to certain toxins and family history.

Treatments vary but may include surgery, chemotherapy, radiation therapy, targeted drug therapy and immunotherapy.

The colon is the final part of the digestive tract. Colon cancer typically affects older adults, though it can happen at any age.
