While men can develop breast cancer, it occurs more frequently in women. In 2011, an estimated 230,480 women will develop breast cancer, compared to 2,140 men, according to the National Cancer Institute.
The main two types of breast cancer are ductal carcinoma, which starts in the ducts of the breast, and lobular carcinoma, which starts in the area of the breast that produces milk.
In early breast cancer, patients usually do not have symptoms. MedlinePlus noted that as the cancer gets larger, symptoms such as a breast lump, fluid from the nipple, or change of the breast or nipple can develop.
In advanced breast cancer, patients can experience weight loss, skin ulcers, bone pain, swelling of the arm next to the affected breast, and breast discomfort.
In the United States, an estimated 46,470 women will develop endometrial cancer in 2011, stated the National Cancer Institute. A common type of uterine cancer, endometrial cancer starts in the endometrium, which is the lining of the uterus. MedlinePlus noted that the majority of endometrial cancer cases begin between ages 60 and 70.
Patients with endometrial cancer who have not gone through menopause can have bleeding between their normal periods, while patients who have gone through menopause can have vaginal bleeding or spotting, and may also have thin clear or white vaginal discharge. Endometrial cancer may cause pelvic cramping or lower abdominal pain.
An estimated 21,990 women will be diagnosed with ovarian cancer in 2011, according to the National Cancer Institute. MedlinePlus added that it is the fifth most common cancer in women.
While the symptoms of ovarian cancer are vague, women should seek medical attention if they have pelvic pain, feel full quickly or bloating daily for several weeks.
The National Cancer Institute noted that in 2011, about 12,710 women will be diagnosed with cervical cancer.
