Breast cancer in stages
Breast cancer is divided into 0, 1st, 2nd, 3rd and 4th periods, four of which are final and three partial, based on the size of the swelling, lymphocytes and long-range transfer. Based on molecular stratification, breast cancer can be classified as LuminalA, LuminalB, Her2-positive and triple-negative breast cancer, with different types of breast cancer treatment.
Introduction to breast cancer
Breast cancer in stages. Medically, now, it must be known that we are divided into two periods, the traditional TNM, the current molecular stratification, the size of the lump, the diameter of the cancer, the lymph knot of the armpit, or the lymph knot of the upper collarbone, the number of transfers, including the lymph knot of this place, whether it has been transferred, and the third is whether it has been moved far away, so this is called the TNM split. We call it the diameter of the swelling, the number of lymph knots, the parts, and whether there is a long-range transfer for a period.
TNM phased
It is divided into zero, one, three, three and four, four of which are final and three partial. Zero, one and two are all early breast cancer, so it is divided into early breast cancer. In our medical sense, we do not have a medium-term medical score, but people like to ask if I am a medium-term one, and in the medium-term it is our medical, local late-stage breast cancer, based on the traditional TNM schedule.
Molecular Fraction
There is another type of stratification, because, with the progress of medicine, we now call it the molecular stratification, which now affects the prognosis and the clinical guidance treatment, unlike that breast cancer, we have a molecular stratification, which is an indicator for everyone, estrogen receptor, congener hormone receptor, human skin growth factor, and a value-added indicator called Ki-67. Depending on the four indicators, they are divided into several categories and are grouped into four.
Breast cancer, LuminalA
A breast cancer called LuminalA, which is not very sensitive to chemotherapy, often benefits from endocrine treatment, which does not necessarily involve a small number of breast cancers that avoid chemotherapy, which is the only type of patient.
Breast cancer, LuminaB
The second type of breast cancer, called Lumina B, is effective chemotherapy, endocrinology treatment and, in some cases, target treatment.
Her2 positive breast cancer
The third type of breast cancer, then, is Her2 positive breast cancer, this type of breast. Target treatment must be used.
Third-negative breast cancer
When we talk about triple-negative breast cancer, the problem with this type of breast cancer is that it’s less endocrine and less target-oriented, and its three results are all negative, and this type of breast cancer is mainly based on chemotherapy, so we now have clinically, in this theory of breast cancer, an individualized treatment for the patient based on two phased approaches.
