How many days does chemotherapy for breast cancer take?

Breast cancer is a major disease that endangers women's lives. Many patients will use chemotherapy to control the disease when the disease is discovered, but many patients do not know the specific chemotherapy time. So how many days does chemotherapy for breast cancer take? Let's take a look.

How many days does chemotherapy for breast cancer last?

Generally speaking, chemotherapy is given about once every 21 days. The reason for this interval is that chemotherapy drugs can produce bone marrow suppression, causing a sharp drop in the number of white blood cells. At this time, the patient can no longer receive chemotherapy, so a period of rest is needed.

Under what circumstances does breast cancer require chemotherapy?

1. Breast cancer patients without distant metastasis receive neoadjuvant chemotherapy with systemic cytotoxic drugs before surgery.

2. Adjuvant chemotherapy can be used to reduce the probability of postoperative recurrence. However, if any of the following conditions are met, chemotherapy may be considered not to be performed:

The lesion is smaller than 1 cm;

The patient's pathological classification was grade I;

No axillary lymph nodes metastasized;

Estrogen and progesterone receptors are positive;

Under 39 years old. Generally speaking, 6 chemotherapy sessions are required after surgery. At the same time, it is best to cooperate with Chinese medicine for auxiliary treatment.

3. It is especially important for premenopausal patients with advanced breast cancer. For postmenopausal patients, if estrogen and progesterone receptors are positive, endocrine therapy should be considered first, but if the effect is still not good after 1 month, chemotherapy can be used. In addition, if these patients do not have axillary lymph node metastasis and the lesions are relatively large, chemotherapy should still be used first.
