Breast cancer: treatment options
Reviewed on July 17, 2026
Receiving a breast cancer diagnosis often brings a whirlwind of emotions, and every feeling is valid. It is reassuring to know that breast cancer is among the most studied tumors, with effective and increasingly personalized treatments. Understanding the available options can help you take an active part in decisions, always alongside a trusted multidisciplinary team.
Local treatments: surgery and radiotherapy
Local treatment acts directly on the breast and the nearby region. Surgery may be conservative, removing only the tumor and a safety margin, or more extensive, depending on the case. Assessment of the lymph nodes is also part of the planning.
Radiotherapy often complements conservative surgery and, in some situations, is also recommended after larger removals, helping to lower the risk of the disease returning in the treated area.
Systemic treatments
Systemic treatments reach the whole body and include chemotherapy, hormone therapy, targeted therapies and, in some cases, immunotherapy. The choice depends greatly on the tumor's biological features.
Markers such as hormone receptors and HER2 guide which medicines tend to be most effective, making treatment increasingly individualized.

Send your exams and your case history and receive a structured, written opinion from an independent specialist physician.
Request a second opinionWhat shapes the decisions
The plan takes into account the stage, the tumor subtype, your age and general health, as well as your preferences and priorities. There is no single right answer for every case.
That is why decisions are usually built together by a team that may include breast surgeons, oncologists, radiation oncologists and other professionals, always with your participation.
Why a second opinion helps
In breast cancer there is often more than one reasonable path, and small differences in interpretation can change the recommendations. Seeking a second opinion is common and encouraged, helping you choose with more confidence.
An independent specialist can review your exams and reports, confirm the diagnosis and staging and comment on the proposed treatment options, offering clarity at such an important moment.
Frequently asked questions
Does every breast cancer surgery remove the whole breast?
No. In many cases conservative surgery is possible, removing only the tumor and a margin around it. The choice depends on the size and location of the tumor, among other factors assessed by the team.
Is chemotherapy always necessary?
Not always. The need for chemotherapy depends on the tumor's features and the stage. In some cases, specific tests help identify who truly benefits from this treatment.
