Is ILC breast cancer aggressive? But ILC tumors can often spread aggressively. People diagnosed with ILC are on average 3 years older at diagnosis compared with those with IDC. ILC is also most often diagnosed at a more advanced stage.
Is ILC worse than IDC? In the subgroup analysis stratified by negative hormone receptor and positive lymph node status, we found that the prognosis of ILC was significantly worse compared to IDC.
What is the best treatment for ILC? Treatment. Treatment of ILC will depend on the characteristics of the tumor present, including the type, size and spread of the tumor. Treatment will generally involve surgery to remove the abnormal cells as well as additional treatment such as radiation therapy or chemotherapy.
What causes ILC breast cancer? It’s not clear what causes invasive lobular carcinoma. Doctors know that invasive lobular carcinoma begins when cells in one or more milk-producing glands of the breast develop mutations in their DNA. The mutations lead to the inability to control cell growth, which results in the cells dividing and growing rapidly.
