Lung cancer

Lung cancer is the leading cause of cancer deaths in the U.S. and worldwide. The 2 major forms of lung cancer are nonsmall cell lung cancer and small cell lung cancer (see 182280), which account for 85% and 15% of all lung cancers, respectively. Nonsmall cell lung cancer can be divided into 3 major histologic subtypes: squamous cell carcinoma, adenocarcinoma, and large cell lung cancer. Cigarette smoking causes all types of lung cancer, but it is most strongly linked with small cell lung cancer and squamous cell carcinoma. Adenocarcinoma is the most common type in patients who have never smoked. Nonsmall cell lung cancer is often diagnosed at an advanced stage and has a poor prognosis (summary by Herbst et al., 2008). [from OMIM]

Uterine leiomyoma

Uterine fibroids are the most common benign tumors in women of childbearing age. Fibroids are made of muscle cells and other tissues that grow in and around the wall of the uterus, or womb. The cause of fibroids is unknown. Risk factors include being African American or being overweight. Many women with fibroids have no symptoms. If you do have symptoms, they may include. -Heavy or painful periods or bleeding between periods . -Feeling full in the lower abdomen . -Urinating often . -Pain during sex . -Lower back pain . -Reproductive problems, such as infertility, multiple miscarriages or early labor. Your health care provider may find fibroids during a gynecological exam or by using imaging tests. Treatment includes drugs that can slow or stop their growth, or surgery. If you have no symptoms, you may not even need treatment. Many women with fibroids can get pregnant naturally. For those who cannot, infertility treatments may help.
