Cancer Care

Fremont and San Leandro Medical Centers


One of the most important tools we have to fight breast cancer is early detection with regular screening. When diagnosed early, treatment is often more effective and less complex. 

Understanding breast cancer and what to expect can help you make informed decisions about your care. 

We’ll talk together about your best treatment options. Treatment methods depend on the location of the tumor and the severity of the cancer. We may recommend one or more options, such as: 

  • Surgery
  • Chemotherapy
  • Radiation therapy
  • Hormonal therapy
  • Biologic therapy
  • Targeted therapy

A diagnosis of breast cancer can be overwhelming. We’ll provide you with the best treatment and support available.


We use the most current surgical techniques available to treat breast cancer. 

The kind of surgery depends on the type and stage of the breast cancer. We may remove the tumor but spare the breast (lumpectomy). Or we may need to remove the entire breast (mastectomy).

After a mastectomy, you may choose to have breast reconstruction surgery.


Chemotherapy uses drugs to kill cancer cells. It’s usually given through intravenous (IV) infusion. The drug used depends on the type and extent of the breast cancer.

Typically, chemotherapy circulates throughout your entire body (systemic) to destroy cancer cells that travel outside of the breast and lymph nodes.

It targets cells that grow and multiply rapidly, such as cancer cells. It can also affect normal cells and cause side effects, such as:  

  • Hair loss
  • Early menopause symptoms, such as hot flashes and vaginal dryness
  • Fatigue
  • Nausea and vomiting

We can help you manage all side effects. 

Call us right away or seek emergency care if you develop signs of infection, such as fever and chills.

Chemotherapy and fertility. Some women may have difficulty getting pregnant (infertility) after chemotherapy. We can talk about this possible side effect when we create your personal treatment plan.

Hormonal Therapy

Most breast cancers test positive for hormones (estrogen or progesterone receptor). Hormonal therapy can greatly reduce the risk of this type of breast cancer returning (relapse). 

Hormones are naturally produced by the body, primarily by the ovaries before menopause. After menopause, estrogen is produced mostly from: 

  • Enzymes in fat cells.
  • Muscle, liver, skin, and other organs or tissues.

Hormonal therapy is usually given for 5 years or longer. Clinical trials are testing to see if taking it longer than 5 years is helpful.  

  • Before menopause, we may prescribe a therapy (tamoxifen) that blocks the production of estrogen from your ovaries. 
  • After menopause, we may prescribe a therapy (aromatase inhibitor) to lower the risk of tumor growth. It decreases estrogen (estradiol) production. 

Hormonal therapy can cause side effects, such as hot flashes, vaginal dryness, and hair thinning.

Targeted Therapy

Targeted therapy uses drugs that target specific parts of the cancer cell. Because they specifically aim for the cancer cells, there’s less damage to healthy cells.

We may recommend it for early stage breast cancer, specifically for HER2-positive breast cancer. We may combine targeted therapy (trastuzumab or other HER2 therapies) with chemotherapy. 

If the cancer has spread (metastasized), we may treat it with targeted therapy alone or along with: 

  • Chemotherapy
  • Hormonal therapy

Several HER2-targeted drugs can reduce the risk of breast cancer relapse for early-stage breast cancer that’s positive for HER2. There are many other targeted therapy drugs being tested in clinical trials. Some have shown promising results.

Radiation Therapy

Radiation therapy uses high-energy beams to kill tumor cells. The most common type is external-beam radiation therapy. A machine outside the body delivers radiation directly to the tumor and nearby tissue. We use a CT scan to identify the precise location first.

You may have radiation therapy:

  • After surgery, to prevent cancer from recurring in the affected breast, chest wall, and surrounding lymph nodes.
  • Instead of surgery, if surgery isn’t an option.
  • To help manage pain when breast cancer spreads to the bones.

You usually receive radiation therapy 5 days a week for 3 to 6 weeks. The length of time depends on the type of breast cancer and how far it’s spread. 

Side effects are common and depend on the stage of the cancer and location of the radiation. For example, you might have: 

  • Fatigue
  • Swollen tender breast with possible blistering
  • Other side effects 

Regardless of the side effects, we’ll help you manage them.

Clinical Trials

We’re always looking for new and better ways to treat breast cancer. Clinical trials are research studies that test new treatments and procedures. 

We can talk about available clinical trials that may be right for you.

If you have an emergency medical condition, call 911 or go to the nearest hospital. An emergency medical condition is any of the following: (1) a medical condition that manifests itself by acute symptoms of sufficient severity (including severe pain) such that you could reasonably expect the absence of immediate medical attention to result in serious jeopardy to your health or body functions or organs; (2) active labor when there isn't enough time for safe transfer to a Plan hospital (or designated hospital) before delivery, or if transfer poses a threat to your (or your unborn child's) health and safety, or (3) a mental disorder that manifests itself by acute symptoms of sufficient severity such that either you are an immediate danger to yourself or others, or you are not immediately able to provide for, or use, food, shelter, or clothing, due to the mental disorder.
