Can radiation alone cure breast cancer?
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.
For some people, radiation may be the only treatment you need. But, most often, you will have radiation therapy with other cancer treatments, such as surgery, chemotherapy, and immunotherapy. Radiation therapy may be given before, during, or after these other treatments to improve the chances that treatment will work.
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.
The standard schedule for getting whole breast radiation is 5 days a week (Monday through Friday) for about 6 to 7 weeks.
Your cells normally grow and divide to form new cells. But cancer cells grow and divide faster than most normal cells. Radiation works by making small breaks in the DNA inside cells. These breaks keep cancer cells from growing and dividing and cause them to die.
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).
When it comes to early stages of disease, patients very frequently do well with either brachytherapy or external beam radiation. Success rates of around 90% or higher can be achieved with either approach.
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)

- Fatigue.
- Hair loss.
- Skin changes.
- Throat problems, such as trouble swallowing.
- Cough.
- Shortness of breath.
If early-stage breast cancer hasn't spread, radiation therapy after a lumpectomy significantly reduces the risk of cancer coming back by approximately 50%. Studies show that a lumpectomy followed by radiation therapy is as effective as a mastectomy without radiation therapy.
Do all breast cancer patients need radiation?
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.
Intracavitary brachytherapy or MammoSite- A radiation bead is placed in the surgical cavity (the space left in the breast tissue after the breast lump is removed). This can be done at the time of surgery or later. Interstitial brachytherapy- Several catheters are placed into the surgical cavity.
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.
For some people with early-stage breast cancer, the time needed for daily radiation therapy after breast-conserving surgery (lumpectomy) can safely be shortened from about 4–6 weeks to 3 weeks, an NCI-funded clinical trial has found.
Conventional dose of 45 Gy to 50 Gy is delivered to the whole breast, followed by a boost to the lumpectomy bed for an additional 10 Gy to 16 Gy. Conventional fractionation typically given over 6 weeks. Depending on the risk of recurrence, radiation therapy is also delivered to regional nodes to 45 GY to 50 Gy.
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.
If radiotherapy doesn't kill all of the cancer cells, they will regrow at some point in the future. We have more information about radiotherapy treatment. Some immunotherapies or targeted cancer drugs may get rid of a cancer completely. Others may shrink the cancer or control it for some months or years.
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. This reduces the risk of the cancer coming back (recurrence) and the risk of passing away from breast cancer.
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.
Your follow-up care may include regular physical examinations, medical tests, or both. Doctors want to keep track of your recovery in the months and years ahead. Annual mammography and physical exams are the only recommended surveillance strategy in people in good health who have been treated for curable breast cancer.
What happens after you finish radiation for breast cancer?
In time radiotherapy can cause the breast tissue to change shape or shrink in size a little. This can happen to your natural breast tissue or a reconstructed breast. After radiotherapy, the breast might feel hard and less stretchy. This is due to a side effect called radiation fibrosis.
However, as well as saving lives by treating tumours, stray radiation also has the ability to damage healthy tissue and it can cause side effects ranging from skin damage and fatigue to serious organ damage, depending on the part of the body that has been treated and the dose delivered to the healthy tissue.
Research has shown that radiation and surgery are equally effective at treating the disease, however, in recent years, radiation treatment has become the preferred treatment option as it causes fewer side effects.
Just one week of radiation therapy after surgery for early-stage breast cancer is as safe and effective as longer courses, researchers report. Radiation therapy for early-stage breast cancer once stretched out over many weeks; the current international standard involves higher doses spaced out over three weeks.
When Is Radiation Therapy Necessary? Radiation therapy is an effective treatment for many types of cancers and studies suggest that it may be involved in up to 60% of all cancer patient's care at some point.
Most women undergo surgery for breast cancer and many also receive additional treatment after surgery, such as chemotherapy, hormone therapy or radiation. Chemotherapy might also be used before surgery in certain situations.
For most people, the cancer experience doesn't end on the last day of radiation therapy. Radiation therapy usually does not have an immediate effect, and it could take days, weeks or months to see any change in the cancer. The cancer cells may keep dying for weeks or months after the end of treatment.
Additionally, vitamin D can also regulate the TME and may even lead to immunostimulation by blocking immunosuppression following radiation.
Nausea and vomiting can occur after radiation therapy to the stomach, small intestine, colon or parts of the brain. Your risk for nausea and vomiting depends on how much radiation you are getting, how much of your body is in the treatment area, and whether you are also having chemotherapy.
Don't wear tight clothing over the treatment area. It's important not to rub, scrub or scratch any sensitive spots. Also avoid putting anything that is very hot or very cold—such as heating pads or ice packs—on your treated skin.
Does breast radiation make you sick?
Nausea is rare with radiation therapy to the breast. You won't lose the hair on your head. However, you may lose some hair under your arm or on the breast or chest area getting radiation (this may be a concern for some men with breast cancer).
Although a patient's decision to refuse cancer treatment may be hard to accept by the physician, this option is well within their rights. Women with a diagnosis of breast cancer can refuse their treatment partly or completely. The reasons for such decisions could be multifactorial.
Historical data of untreated breast cancer patients reveal a potential for long survival in some cases. The spectrum of clinical aggressiveness of breast cancer varies between virulence and chronic disease.
About 70 percent of women with hormone receptor (HR)-positive, HER2-negative, axillary lymph node-negative breast cancer—including those with mid-range scores on the cancer recurrence scale—do not benefit from chemotherapy [1].
“Ductal” refers to the milk ducts in the breast, and “in situ” means “in its original place.” DCIS is a stage 0 cancer, which is the earliest and generally the most treatable form of breast cancer. Although DCIS is noninvasive when it's diagnosed, over time it can become invasive.
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.
The use of radioactive implants (known as brachytherapy) usually involves the insertion of metal wires, seeds or tubes near the cancerous cells. These implants are often used to treat areas of the body where an implant can be placed inside the body without surgery.
It often takes 3 to 4 weeks for skin reactions to heal. If you have any questions or concerns, don't hesitate to contact your radiation oncologist or nurse.
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.
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.
Is surgery and radiation enough for stage 1 breast cancer?
Stage 1 is highly treatable, however, it does require treatment, typically surgery and often radiation, or a combination of the two. Additionally, you may consider hormone therapy, depending on the type of cancer cells found and your additional risk factors.
If surgery to remove the cancer is not possible, it is called inoperable. The doctor will then recommend treating the cancer in other ways. Chemotherapy, immunotherapy, targeted therapy, radiation therapy, and/or hormonal therapy may be given to shrink the cancer.
At the same time, if a cell doesn't divide, it also cannot grow and spread. For tumors that divide slowly, the mass may shrink over a long, extended period after radiation stops. The median time for a prostate cancer to shrink is about 18 months (some quicker, some slower).
Radiation therapy usually does not have an immediate effect, and it could take days, weeks or months to see any change in the cancer. The cancer cells may keep dying for weeks or months after the end of treatment. It may be some time before you know whether the radiation therapy has controlled the 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.
Hormone therapy may be used as the only treatment for breast cancer if your general health prevents you having surgery, chemotherapy or radiotherapy.
Using Medicare reimbursement data, the researchers estimated that the cost per patient for the conventional, six-week radiation therapy was more than $13,000. That compared to a little more than $8,000 for the shorter regimen or no cost when radiation is eliminated.
In a complete remission, all signs and symptoms of cancer have disappeared. If you remain in complete remission for 5 years or more, some doctors may say that you are cured. Still, some cancer cells can remain in your body for many years after treatment. These cells may cause the cancer to come back one day.
