Stage 0
Breast cancer at stage zero, atypical cells are not or have not spread beyond the lobule as a channel or milk-producing Organs, into the surrounding breast tissue. Referred to as carcinoma in situ, and divided into two types:
1. Ductal carcinoma in situ (DCIS) – in this case is a very early stage, cancer can be cured and very survivable. If not treated or not detected, it can spread to surrounding breast tissue.
2. Lobular carcinoma in situ (LCIS) – are not cancer but an indicator that identifies women have an increased risk of developing breast cancer.
Stage 1 – is the early stage invasive breast cancer
At stage 1 breast cancer, cancer size no larger than two centimeters (about an inch) and has not spread to surrounding lymph nodes or outside the breast.
Stage 2
At stage 2 breast cancer, divided into two categories according to tumor size and whether the cancer has spread to the lymph nodes.
Stage 2 A
Breast Cancer in tumor size less than two centimeters (about an inch) and has spread to three lymph nodes armpit Assistants. and the tumor has grown more than two centimeters, but not greater than five centimeters.
Stage 2 B
Cancer or a tumor has grown to between two and five centimeters and has spread to three lymph nodes armpit Assistants. Or, tumors larger than five centimeters, but has not spread to the lymph nodes around it.
Stage 3
Stage 3 A
Breast cancer or a tumor larger than two centimeters, but less than five centimeters and has spread to up to nine Assistants armpit lymph nodes.
Phase 3 B
The cancer has spread to tissues near the breast including the skin, chest wall, ribs, muscle, or lymph nodes in the chest wall or above the collarbone.
Stage 4
The cancer has spread and damage to Organs or other body tissues, including liver, Lungs, brain, skeletal system, or lymph nodes near the collarbone.
