Is invasive ductal carcinoma the mildest form of breast cancer?

1. Invasive ductal carcinoma is not the mildest type of breast cancer. Generally speaking, breast carcinoma in situ is the mildest pathological type of breast cancer. Invasive ductal carcinoma is only the most common pathological type of breast cancer and belongs to non-special invasive breast cancer. In addition, there are special types of invasive breast cancer such as invasive lobular carcinoma, mucinous adenocarcinoma, adenosquamous carcinoma, malignant lymphoma, small cell carcinoma, etc.

2. Since carcinoma in situ is limited to the mucosa and there is no basement membrane invasion, the cure rate of patients after surgical resection is very high and most patients can survive for a long time. Therefore, the patient's condition is relatively mild. Invasive ductal carcinoma breaks through the mucosa and spreads outside the mucosa.

3. It is not the mildest clinically. If distant organs metastasize, the survival time of patients with invasive ductal carcinoma will be significantly shortened. However, by taking active anti-cancer treatment measures, such as endocrine therapy, targeted therapy, systemic chemotherapy, local radiotherapy, etc., most patients can also prolong their survival.
