The length of hospitalization for breast cancer patients is determined on a case-by-case basis, and there is no definitive data to support this. Generally speaking, patients who can be treated surgically usually have less hospitalization time, while patients who are treated conservatively have longer hospitalization time, with great individual differences. For patients with breast cancer that is detected early enough to be cured by surgery, the number of days in the hospital usually ranges from a few days to a dozen days. If there are post-operative complications, the hospital stay is likely to be extended accordingly. Generally speaking, the larger the scope of the surgery, the more traumatic it will be for the patient, the longer the recovery time will be, and the hospitalization time will be extended accordingly. For patients with conservative treatment, they can be treated by radiotherapy, targeted therapy, immunotherapy, etc., ranging from 3 to 7 days to 1 to 2 months. Breast cancer patients need to go to regular hospitals, consult professional doctors, cooperate with doctors to complete laboratory tests, standardize treatment and avoid blind treatment.
