Stage 0: abnormal cells found in the milk ducks or milk-producing glands. These cells have not spread beyond the ducts or glands.
Treatments: Lumpectomy (removal of lump) if localised; Mastectomy (removal of breast) if found in multiple sites; Radiotherapy.
Stage 1: cancer has formed, with a tumor not larger than 2cm but has not spread outside the breast or clusters of cancer calls are found in lymph nodes inside the breast.
Treatments: Mastectomy; Lumpectomy+raditherapy; Lumpectomy alone; Hormonal therapy (for people with hormone-receptor-positive cancer)
Stage 2: the tumor is between 2cm and 5cm, with or without spread to the axillary nodes (under the arm); clusters of cancer cells are found in the axillary nodes.
Tratments: Radical mastectomy with or without radiotherapy;Lumpectomy +radiotheray; Chemotherapy; Hormonal therapy; Targeted therapy (e.g. for cancers with too many HER2 protein receptors).
Stage 3: the tumor is larger than 2cm and has spread to the axillary lymph nodes; cancer cells are found in lymph nodes near the breast bone, the chest wall or the skin of the breast.
Treatments: Radical mastectomy with or without radiotherapy;Lumpectomy +radiotheray; Chemotherapy; Hormonal therapy; Targeted therapy
Stage 4: the cancer has spread to other organs of the body, most often the bones, lungs, liver or the brain.
Treatments: Surgery, radiation, hormonal therapy, targeted therapy, treatments to relieve pain and vomiting, palliative care.
Having learned the above,what is your thought?
To me, prevention is better than cure. Take less meat produced from modern farming where growth hormone is applied.
