Stage 3 What does it mean to have Stage 3 breast cancer? Stage 3 cancer means the breast cancer has extended to beyond the immediate region of the tumor and may have invaded nearby lymph nodes and muscles, but has not spread to distant organs. Although this stage is considered to be advanced, there are a growing number of effective treatment options. This stage is divided into three groups: The difference is determined by the size of the tumor and whether cancer has spread to the lymph nodes and surrounding tissue. Stage 3A Breast cancer means one of the following descriptions applies.
Abstract Mammary carcinomas and adenocarcinomas MACs are relatively common tumors in cats. The postexcisional survival period of affected cats is inversely proportional to tumor size, but the reported median survival periods for different tumor size categories is quite variable. This variability diminishes the prognostic value of reported data. In our study, cats with MACs greater than 3 cm in diameter had a month median survival period, whereas those with MACs less than 3 cm in diameter had a month survival period. Survival periods for cats with MACs smaller than 3 cm ranged from 3 to 54 months; therefore, tumor size alone is of limited prognostic value in cats with MACs smaller than 3 cm in diameter. In cats with MACs larger than 3 cm in diameter, tumor size appears to have much higher prognostic relevance, because this study, as well as others, have indicated that cats with MACs greater than 3 cm in diameter have a poor prognosis, with median survival periods ranging from 4 to 12 months.
Cells in the body normally divide reproduce only when new cells are needed. Sometimes, cells in a part of the body grow and divide out of control, which creates a mass of tissue called a tumor. If the cells that are growing out of control are normal cells, the tumor is called benign not cancerous. If, however, the cells that are growing out of control are abnormal and don't function like the body's normal cells, the tumor is called malignant cancerous. Cancers are named after the part of the body from which they originate.
The stage of the cancer helps you and your doctor: Your doctor will begin to determine this during surgery to remove the cancer and look at one or more of the underarm lymph nodes, which is where breast cancer tends to travel first. He or she also may order additional blood tests or imaging tests if there is reason to believe the cancer might have spread beyond the breast. The AJCC is a group of cancer experts who oversee how cancer is classified and communicated.
