Breast cancer is cancer that develops from breast tissue.Signs of breast cancer may include a lump in the breast, a change in breast shape, dimpling of the skin, fluid coming from the nipple, or a red scaly patch of skin. In those with distant spread of the disease, there may be bone pain, swollen lymph nodes, shortness of breath, or yellow skin.

Causes Of Breast Cancer :-
Risk factors for developing breast cancer include:
female sex
obesity
lack of physical exercise
drinking alcohol
hormone replacement therapy during menopause
ionizing radiation
early age at first menstruation
having children late or not at all
older age,
and family history

SYMPTOMS:-

The first noticeable symptom of breast cancer is typically a lump that feels different from the rest of the breast tissue. More than 80% of breast cancer cases are discovered when the woman feels a lump.[15] The earliest breast cancers are detected by a mammogram.[16] Lumps found in lymph nodes located in the armpits[15] can also indicate breast cancer.

Inflammatory breast cancer is a particular type of breast cancer which can pose a substantial diagnostic challenge. Symptoms may resemble a breast inflammation and may include itching, pain, swelling, nipple inversion, warmth and redness throughout the breast, as well as an orange-peel texture to the skin referred to as peau d'orange;[15] as inflammatory breast cancer doesn't show as a lump there's sometimes a delay in diagnosis.

Another reported symptom complex of breast cancer is Paget's disease of the breast. This syndrome presents as skin changes resembling eczema, such as redness, discoloration, or mild flaking of the nipple skin. As Paget's disease of the breast advances, symptoms may include tingling, itching, increased sensitivity, burning, and pain. There may also be discharge from the nipple. Approximately half of women diagnosed with Paget's disease of the breast also have a lump in the breast
