When a breast cell undergoes a series of genetic mutations, and escapes the monitoring of the body's immune system, after a long period of development (or even decades), it gradually becomes a cancer cell, and then 1 cancer cell becomes 2, 2 becomes 4, so that at least 30 times will develop into a detectable nodule. Therefore, some patients say that they have this nodule decades ago, this statement is not true, they may have a benign nodule decades ago or the gland they touched as a nodule, and then recently a new tumor but do not know it, it is still necessary to have regular physical examination in a regular medical institution.
How fast does breast cancer grow?
Different types of breast cancer grow at different rates, and there is relatively little research in this area because doctors cannot let the tumor grow without intervention after it is found. A foreign study in 2018 showed that comparing the size of the tumor when the tumor was first found by ultrasound and the size of the tumor at the time of surgery, the interval between the middle was about 57 days on average (the waiting period for hospitalization in foreign countries is relatively long), and it was found that 36% of the patients had no significant change in tumor size, 64% of the patients had increased their tumor, and the average tumor volume increased by 34 compared with before5 per cent, that is, an increase of almost a third. As the tumor grows, it grows faster. An earlier study showed that fast-growing tumors doubled in size in 25 days, while slow-growing tumors doubled in size in 76 days or more. No matter how fast the tumor grows, the earlier it is diagnosed, the sooner it is.
What causes breast cancer to grow faster?
There are some early breast cancers that can have a chronic course, mainly manifested as small lumps in the breast, which generally do not attract attention, and without diagnosis and treatment, after a period of time, the tumor will increase significantly, and the symptoms of ** will appear, or the axillary lymph nodes are swollen, and then it is relatively late to check the stage of breast cancer, and it is more difficult to distance **and**.
Therefore, once the clinical early detection of breast mass has the highest quality, go to the hospital in time, which is conducive to early detection, early diagnosis and early development, the speed of breast cancer growth in clinical practice, and the individual differences of patients are related, some patients have breast malignant tumors, the early growth is slow, the symptoms are not obvious, if the patient finds the malignant tumor in time, the later growth rate is fast.
Some patients have poor autoimmunity and poor ability to remove tumor cells, and the tumor growth rate is fast, and the tumor can reach the advanced stage of the tumor in a few months, so the growth rate of breast tumor should be differentiated according to the patient's constitution, resistance, and tumor type.
Can you wait to find breast cancer? Don't have surgery first?
It does not mean that as soon as breast cancer is detected, surgery must be performed immediately, and it is more important to arrange the timing of surgery reasonably than to rush the surgery. Of course, surgery is needed, but it does not mean that it should be done in a hurry. Some breast cancer patients need to have a neoadjuvant for a period of time before surgery** before surgery. Why? Won't there be a delay if you don't have surgery right away**?
The so-called neoadjuvant breast cancer ** refers to the ** performed before surgery**, mainly systemic drugs** (including chemotherapy, targeting**, endocrine**, etc.), and sometimes radiotherapy.
1. It can inhibit or eliminate micrometastases, inhibit or kill the primary tumor and surrounding infiltrating tumor cells, thereby reducing postoperative metastasis.
2. The tumor can be shrunk, so that the locally advanced patients who cannot or are not suitable for surgery can get the opportunity of surgery (preoperative transformation**) or the patients who can not conserve breast can be reduced by preoperative neoadjuvant **, so as to obtain the opportunity of breast conservation.
3. The sensitivity of the tumor to chemotherapy can be understood before surgery, which is very helpful for judging the prognosis and guiding the postoperative choice.
Patients with HER-2-positive breast cancer, triple-negative breast cancer, and patients who wish to conserve breast but have a large ratio of tumor size to breast volume that makes it difficult to conserve breast require neoadjuvant disease followed by surgery.
