Quick Summary

Lobular carcinoma is a type of breast cancer that originates in the milk-producing lobules of the mammary glands. It accounts for fewer than 15 percent of all breast cancer cases. While most breast cancers start in the milk ducts (ductal carcinomas), lobular carcinomas begin in the lobules. These are both types of adenocarcinomas because they arise from glandular tissue. Early diagnosis and treatment are crucial for improving survival rates, as breast cancer can spread to lymph nodes and other parts of the body. Risk factors include genetic mutations, prolonged exposure to estrogen, obesity, alcohol consumption, and smoking.
