The cause of Breast cancer is not fully understood.
Heredity or genetically related susceptibility is considered to play a role. Hormonal regulation of the breast is related to the development of breast cancer, but the mechanisms are poorly understood. Sex hormones (like estrogen) may act as a tumour promoters id initiating agents have induced malignant changes. Estrogen doesn't cause Breast Cancer, but the initiating agents that are found in a susceptible person may accelerate its growth.
Additional factor under study include physical inactivity, dietary fat intake, obesity, and alcohol intake. Environmental factors such as chemical, pesticide, and radiation exposure may also play a role.
Gene abnormalities may be inherited. 5 to 10 percent of all breast cancer persons inherit this gene. Tumour suppressor genes BRCA-1 gene, located in chromosome 17 is a tumour suppressor gene that inhibits tumor development when functioning normally. Women who have BRCA-1 mutations have a 50-85 percent lifetime chance of developing breast cancer. BRCA-2 is another culprit. BRCA tumor suppressor genes mutations may account for 10-40 percent of breast cancers.
Infertility, Diabetes, obesity, and estrogen therapy place a woman at high risk for endometrial cancer.
There are two types of endometrial cancer, but the causes for either type are not well known. Type 1 is known to be exacerbated by estrogen, though it is not the primary cause.
A salpingo-oophorectomy is necessary when treating ovarian and endometrial cancer because the fallopian tubes and ovaries are the most common sites to which cancer may spread.
Endometrial cancer is cancer of the inner lining of the uterus(womb). Most cancers of the uterus start in the endometrium and are thought to be caused by excess estrogen.
Smoking is the #1 cause of lung cancer in America.

two primary forms, cervical and endometrial. Cancer of the cervix most often affects the neck of the cervix or the opening or the opening into the uterus from the vagina. Endometrial cancer affects the inside lining of the uterus.
Endometrial cancer (uterine cancer) is the most common gynecologic cancer that occurs in the United States; and arises from abnormal cells that develop within the inside lining of the uterus. It occurs most often after menopause, but may also be diagnosed before menopause.

There are twelve types of Cancer most commonly found in the United States.In alphabetical order they are:Bladder Cancer; Breast Cancer; Colon/Rectal Cancer; Endometrial Cancer; Kidney/Renal Cancer; Leukemia; Lung Cancer; Melanoma; Non-Hodgkin Lymphoma; Pancreatic Cancer; Prostate Cancer & Thyroid Cancer.There are other Cancer types as well.
Screening for breast cancer and cervical cancer are the most common types of cancer screening done at Planned Parenthood. Biopsy for endometrial and vulvar cancer are also common services. Offices may also order testing to screen for colon and prostate cancer, and the typical examination will also look for signs of cancer of the thyroid, skin, and testicles.
