Breast cancer is an invasive tumor that develops in the mammary gland. Breast cancer is detected via mammograms, breast self-examination (BSE), biopsy, and specialized testing on breast cancer tissue. Treatment of breast cancer may involve surgery, radiation, hormone therapy, chemotherapy, and targeted therapy. Breast cancer risk may be lowered by managing controllable risk factors.

Bone CancerBone cancer is a rare type of cancer that occurs in cells that make up the bones. Primary bone cancer that arises in bone cells is different than metastatic bone cancer, which is cancer that arises in another part of the body and then spreads to the bones. Hereditary and environmental factors likely contribute to the risk of bone cancer. Signs and symptoms of bone cancer may include pain, the presence of a mass or lump, and bone fractures. There are different types of bone cancer (osteosarcoma, chondrosarcoma, Ewing's sarcoma, pleomorphic sarcoma, fibrosarcoma). Treatment for bone cancer may include surgical removal of the tumor, chemotherapy, radiation, and/or a stem cell transplant. The prognosis for bone cancer depends on the type of cancer and the extent of spread.

CA 125 Ovarian Tumor Marker Blood TestCA 125 is a protein, and a tumor marker or biomarker. CA 125 is present in greater concentration in ovarian cancer cells than in other cells. CA stands for cancer antigen. Increases in CA 125 can also occur with malignant tumors of the Fallopian tubes, lining of the uterus, lung, breast, and gastrointestinal track. Benign conditions such as infections of the abdomen, chest, menstruation, endometriosis, benign tumors of the ovaries, and liver disease can also raise CA 125.
CancerCancer is a disease caused by an abnormal growth of cells, also called malignancy. It is a group of 100 different diseases, and is not contagious. Cancer can be treated through chemotherapy, a treatment of drugs that destroy cancer cells.

Chest X-RayChest X-Ray is a type of X-Ray commonly used to detect abnormalities in the lungs. A chest X-ray can also detect some abnormalities in the heart, aorta, and the bones of the thoracic area. A chest X-ray can be used to define abnormalities of the lungs such as excessive fluid (fluid overload or pulmonary edema), fluid around the lung (pleural effusion), pneumonia, bronchitis, asthma, cysts, and cancers. Normal chest X-ray shows normal size and shape of the chest wall and the main structures in the chest
Fibrocystic Breast DiseaseFibrocystic breast condition (sometimes called fibrocystic breast disease) is characterized by lumpiness and usually pain, tenderness, and discomfort in one or both breasts. The condition is very common and benign (not malignant). Fibrocystic breast condition is the most common cause of "lumpy breasts" in women. A common symptom of fibrocystic breast condition is breast pain or discomfort.
Some women with fibrocystic breasts have mile breast tenderness or pain. Other women with the condition may have very painful and tender breasts with lumpy areas that can be felt. Fibrocystic breast condition is most common in women after age 30, which continues through perimenopause and menopause. Women with the condition often have fewer problems after menopause (postmenopause).
Fibrocystic breast condition that involves hyperplasia is associated with a slightly increased risk of developing breast cancer. Atypical hyperplasia is associated with a moderately increased risk of developing breast cancer compared to women with fibrocystic without fibrocystic changes.
Natural and home remedies to help relieve breast pain include NSAIDs like aspiring, Aleve, and Advil. Prescription medication also may help relieve symptoms of fibrocystic breasts.
Genetic Diseases (Disorder Definition, Types, and Examples)The definition of a genetic disease is a disorder or condition caused by abnormalities in a person's genome. Some types of genetic inheritance include single inheritance, including cystic fibrosis, sickle cell anemia, Marfan syndrome, and hemochromatosis. Other types of genetic diseases include multifactorial inheritance. Still other types of genetic diseases include chromosome abnormalities (for example, Turner syndrome, and Klinefelter syndrome), and mitochondrial inheritance (for example, epilepsy and dementia).
MRI (Magnetic Resonance Imaging Scan)MRI (or magnetic resonance imaging) scan is a radiology technique which uses magnetism, radio waves, and a computer to produce images of body structures. MRI scanning is painless and does not involve X-ray radiation. Patients with heart pacemakers, metal implants, or metal chips or clips in or around the eyes cannot be scanned with MRI because of the effect of the magnet.

Swollen Lymph Nodes (Glands)Lymph nodes help the body's immune system fight infections. Causes of swollen lymph nodes (glands) may include infection (viral, bacterial, fungal, parasites). Symptoms of swollen lymph nodes vary greatly, but may include fever, night sweats, toothache, sore throat, or weight loss. Causes of swollen lymph nodes also vary, but may include cancer, the common cold, mono, chickenox, HIV, and herpes. The treatment of swollen lymph nodes depends upon the cause.
