The rate of progression of invasive breast cancer

The rate of progression of invasive breast cancer is evaluated depending on the condition and stage of the disease in different patients. In case of early or intermediate stage breast cancer, the rate of progression of the disease may be slower. In clinical practice, it can be judged that some patients have a breast cancer lump that may remain untreated for several years and it progresses more slowly. This type of breast cancer is called more inert breast cancer, which is related to its molecular typing and the different characteristics of the patient. However, in some patients, the disease can progress very quickly, with a small lump that may develop into a larger lump in just a few months and a systemic progression. For advanced breast cancer, in terms of clinical symptoms, its development is usually faster, such as brain metastasis, and the patient may have a life-threatening condition in just a few months. Therefore, the rate of development of invasive breast cancer cannot be generalized, but should be analyzed on a case-by-case basis. There is also some diversity and heterogeneity of the patient or some genetic characteristics, with different situations and different staging.
