Breast cancer is one of the most common malignant neoplasms in women, and its development is a multi-step and multi-stage process, which includes the malformation of normal mammograms, pre-cancer pathologies, in situ cancer, leaching and transfer.
1. Malignant mammography
As a result of various carcinogenic factors, normal mammogram cells undergo genetic mutations and are gradually turning to vice.
2. Pre-cancer pathologies
Breast epipelagic cell growth is unusual, with a certain tendency to mutate, but not yet cancer.
3. In situ cancer
Cancer cells are confined to the catheters of the breast or to the leaves, do not break through the substrate and do not have the ability to attack and transfer.
4. Penetrating cancer
Carcinocellular cells break through the base membrane and begin to impregnate to the surrounding tissues and form swelling.
Transfer
Leached cancer can be transmitted to other parts of the body, such as lungs, liver, bones, etc., through the blood or lymphomy system.
Early treatment is generally more effective when in situ cancer and its early detection occurs. Early breast self-screening and breast cancer screening, such as breast ultrasound, mammography, etc., are therefore important for early detection of breast cancer, and for improved cure and survival. In addition, maintaining a healthy lifestyle, such as a reasonable diet, adequate exercise, reduction of alcohol consumption and cessation of smoking, can help prevent breast cancer.
