Common Types of Cancer

Skin Cancer

Skin cancer is the most widespread as well as the most curable form of cancer
Skin cancer may appear in two forms: non-melanoma and melanoma, with the latter being the more serious form
Almost all skin cancers are the result of overexposure to ultraviolet light from natural sunlight or tanning salons

Warning Signs
Spotting skin cancer early on can make all the difference in terms of getting better, and a good method would be to check moles periodically, especially those which:

Moles which are not symmetrical on both sides
Raised moles with an irregular appearance
Moles with uneven or jagged edges
Moles whose diameter exceeds a quarter of an inch
Moles with darkening or changing color noticeably, or having unusual colors such as red, purple, grey, white, or pink

Breast Cancer

After skin cancer, this is the second most common cancer among women
Breast cancer originates with tumors in the breast tissue
Two forms of breast tumors are "in situ", which can be treated and cured; and “invasive”, which is spreading and has grave consequences
A large number of tumors that arise in this area are benign, but there are also cancerous tumors
Catching breast cancer early can mean successful treatment, so be sure to
have regular breast exams and mammograms.

Prostate Cancer

Prostate cancer only occurs in men, and originates in the prostate gland, (which is by the rectum, beneath the bladder)
Prostate cancer is able to grow rapidly and extend to other parts of the body, or it can be localised in the prostate, without growth
Most cases of prostate cancer are the type with low growth rates, seldom causing serious problems

Lung Cancer

Lung cancer can come in two forms: small-cell, and non-small cell
Smoking tobacco is the largest risk factor for the development of lung cancer
The non-small cell form is the more common, typically spreading at a rate relatively slower than the small-cell form
Small cell lung cancer is nearly always caused by smoking

Endometrial and Ovarian Cancer

These forms of cancer usually found in the female reproductive system
Endometrial cancer originates from the womb, in the lining of the uterus, while Ovarian cancer is found in the ovaries, one or both
Endometrial cancer is commonly found in post-menopausal women, and its most telling sign is abnormal bleeding
Ovarian cancer can come in several forms, depending on its size and location. Sadly, ovarian cancer is difficult to detect in its early stages

Rectal Cancer and Colon Cancer

Rectal cancer originates in the area of the large intestine nearest to the anus, the rectum, while colon cancer originates in the colon, or large intestine
Both forms have similar characteristics, as most start off as a polyp, which is a small innocuous growth in the colon wall. The spread and growth of this polyp is what causes cancer

Warning Signs

Cramp-like pains in the lower area of the stomach
Blood in the stool or in the loo, following a bowel movement
A significant change in the appearance of one’s stool
