Cancer

Cancer is known as a malignant neoplasm unregulated cells. Cancer can be detected in a number of ways, including the presence of certain signs and symptoms, screening tests, or medical imaging. Once a possible cancer is detected it is diagnosed by microscopic examination of a tissue sample. In cancer, cells divide and grow uncontrollably, forming malignant tumors, and invade nearby parts of the body. Cancer is usually treated with chemotherapy, radiation therapy and surgery. Some cancers can be felt or seen through the skin - a lump on the breast or testicle can be an indicator of cancer in those locations.

Symptoms also can be created as a tumor grows and pushes against organs and blood vessels. Extracting cancer cells and looking at them under a microscope is the only absolute way to diagnose cancer. This procedure is called a biopsy. After a diagnosis is made, doctors find out how far the cancer has spread and determine the stage of the cancer

malignant, tumors form when two things occur:

1.a cancerous cell manages to move throughout the body using the blood or lymph systems, destroying healthy tissue in a process called invasion

2.that cell manages to divide and grow, making new blood vessels to feed itself in a process called angiogenesis.

Not all environmental causes are controllable, such as naturally occurring background radiation, and other cases of cancer are caused through hereditary genetic disorders. It is not possible to prevent all cases of cancer. Aspiri has been found to reduce the risk of death from cancer by about 7%. The survival rates vary dramatically by type of cancer, with the range running from basically all people surviving to almost no one surviving.People with a "cancer personality"—depressed, repressed, self-loathing, and afraid to express their emotions—were believed to have manifested cancer through subconscious desire. increases patients' anxiety, as they incorrectly believe that natural emotions of sadness, anger or fear shorten their lives.Typically, these are studied in clinical trials to compare the proposed treatment to the best existing treatment.

Breast Cancer is formed by breast tissue the inner lining of milk ducts or the lobules that supply the ducts with milk. Radiation is used after breast-conserving surgery and substantially improves local relapse rates and in many circumstances also overall survival.Symptoms may resemble a breast inflammation and may include itching, pain, swelling, nipple inversion, warmth and redness in the breast. Metastatic disease Unexplained weight loss can occasionally herald an occult breast cancer, as can symptoms of fevers or chills, Bone pain, joint pains.

New symptom should be taken seriously by both patients and their doctors. Healthcare provider and mammography, can offer an approximate likelihood that a lump is cancer, and may also detect some other lesions, such as a simple cyst. Blood are sent out for inspection in breast cancer. The fluid is removed and is sent out for sample analysis by ahealthcare provider. The results of a physical examination by a health care is very often performed in special Circumstances in Mammography, biopsy as the definitive diagnostic and primary treatment method.
