Introduction: Worldwide, breast cancer is the neoplasia that most affects women, after skin cancer, and accounts for 25% of new cases each year. Over the past 40 years, the survival rate has been increasing in developed countries — currently, it is 85% in 5 years —, while in developing countries it remains between 50 and 60%. As such, routine use of mammography throughout the world is considerably important. Objectives: To describe demographic and pathological characteristics in addition to the surgical approach of patients with invasive breast carcinoma in a renowned institution. Methods: A cross-sectional, descriptive study using secondary data obtained from medical records of breast cancer patients operated on at the Cancer Institute of Ceará (ICC), from 2002 to 2012. Data were analyzed using Epi Info 7.0 software. Results: The study population included 746 patients with primary breast tumors, of which 626 (84%) were invasive. Within the invasive breast tumors, the majority (554 – 88.49%) were of the invasive ductal carcinoma (IDC) type. Concerning stages, 351 cases (56.07%) were stage II. The average age of patients was 41 to 50 years old, and T2 tumors measured approximately 2 to 5 cm. The most frequent surgery was a quadrantectomy. A sentinel lymph node biopsy (SNB) was performed in 368 patients (58.78%). Conclusion: O ur c asuistry p rovides i mportant i nformation w ith r egard t o t he p rofile o f p atients s urgically t reated a t a renowned public institution in the Brazilian Northeast. Diagnosing the disease at an advanced stage still occurs at this institution, which results in high rates of mastectomy. Thus, better results tend to be obtained as better screening proposals are provided.
