Is radiation enough for Stage 2 breast cancer?
If you were initially diagnosed with stage II breast cancer and were given a systemic treatment such as chemotherapy or hormone therapy before surgery, radiation therapy might be recommended if cancer is found in the lymph nodes during mastectomy.
Radiotherapy may be used in the early stages of cancer or after it has started to spread. It can be used to: try to cure the cancer completely (curative radiotherapy) make other treatments more effective – for example, it can be combined with chemotherapy or used before surgery (neo-adjuvant radiotherapy)
Luminal A breast cancer accounts for almost 60% of breast cancer diagnoses. It is a slow growing, low-grade cancer that doesn't often spread to other cells, which provides a good prognosis for this group of patients.
In most cases, the standard treatment for early-stage breast cancer is lumpectomy to remove the cancer followed by about 6 weeks of radiation therapy (5 days a week) to destroy any cancer cells that may have been left behind. This two-step approach reduces the risk of breast cancer recurrence (the cancer coming back).
The cancer may come back to the same place as the original primary tumor or to another place in the body. If you remain in complete remission for five years or more, some doctors may say that you are cured, or cancer-free.
Breast cancer can be treated in a variety of ways, including with radiation therapy. Depending on your cancer type and stage, radiation can be used alone as a treatment for breast cancer, or with other therapies.
You will likely have radiation therapy as an outpatient at a hospital or other treatment facility. A common treatment schedule (course) historically has included one radiation treatment a day, five days a week (usually Monday through Friday), for five or six weeks.
it's completely safe as the radiation is highly targeted, no other organs or tissue is ever at risk. The cosmetic results are tremendous, you don't need new breasts or reconstruction surgery. And when detected early has a 95% success rate.
Before surgery, to shrink a cancerous tumor (neoadjuvant therapy) After surgery, to stop the growth of any remaining cancer cells (adjuvant therapy) In combination with other treatments, such as chemotherapy, to destroy cancer cells. In advanced cancer to alleviate symptoms caused by the cancer.
A study has found that postmenopausal women who stop taking hormonal therapy early or skip doses are much more likely to have a breast cancer recurrence than women who take hormonal therapy as prescribed.
What happens if you don't have radiation for breast cancer?
Missed Radiation Therapy Sessions Increase Risk of Cancer Recurrence. Patients who miss radiation therapy sessions during cancer treatment have an increased risk of their disease returning, even if they eventually complete their course of radiation treatment, according to a new study.
Stages I-III
Treatment for stages I to III breast cancer usually includes surgery and radiation therapy, often with chemo or other drug therapies either before (neoadjuvant) or after (adjuvant) surgery.

Even though Stage 0 breast cancer is considered “non-invasive,” it does require treatment, typically surgery or radiation, or a combination of the two. Chemotherapy is usually not part of the treatment regimen for earlier stages of cancer.
You can lower your risk by getting radiation therapy afterward. You have a 3% to 15% chance of breast cancer recurrence within 10 years with this combined treatment. Based on genetic testing, your provider may recommend additional treatments to further reduce your risk.
The type of radiation treatment you get depends on the stage of breast cancer. People with early to stage 3 breast cancer will benefit most from radiation treatment. Radiation can also help ease side effects in people with advanced breast cancer.
In most cases, recurrent cancers appear within the first three years after treatment. But in some cases, the disease may return many years later, either locally or in distant organs in the body.
Aggressive, hard-to-treat breast cancers, such as inflammatory breast cancer (IBC) and triple-negative breast cancer (TNBC), are the types most likely to recur.
For women who have lumpectomy plus radiation therapy, the chance of a local breast cancer recurrence in 10 years is about 3-15 percent [165-166]. The risk of local recurrence depends on tumor characteristics, including biomarkers (such as hormone receptor status and HER2 status).
Radiation therapy is recommended for most people who have lumpectomy to remove breast cancer. Lumpectomy is sometimes called breast-conserving surgery. The goal of radiation after lumpectomy is to destroy any individual cancer cells that may have been left in the breast after the tumor was removed.
Radiation to the breast can sometimes damage some of the nerves to the arm. This is called brachial plexopathy and can lead to numbness, pain, and weakness in the shoulder, arm, and hand. Radiation to the underarm lymph nodes might cause lymphedema, a type of pain and swelling in the arm or chest.
Is your immune system weaker after radiation for breast cancer?
Certain cancer treatments (such as chemotherapy, radiation therapy, surgery, stem cell or bone marrow transplant, or steroids) or the cancer itself can suppress or weaken the immune system. These treatments can lower the number of white blood cells (WBCs) and other immune system cells.
“Despite the less aggressive breast cancers typically diagnosed in this population, most patients who undergo [lumpectomy] continue to be treated with whole breast radiation therapy after surgery.
External beam radiation therapy is offered after breast-conserving surgery for stage 1 breast cancer. All of the breast and the lymph nodes under the arm and near the collarbone are treated.
Radiation can give you fatigue that gets worse over time (called cumulative fatigue). It usually lasts 3 to 4 weeks after your treatment stops, but it can continue for up to 3 months. Hormone therapy deprives the body of estrogen, and that can lead to fatigue that may last throughout your treatment or longer.
