Radiotherapy For Breast Cancer
Radiotherapy uses high energy x-rays to kill cancer cells. You usually have 3 weeks of radiotherapy after having breast conserving surgery. But in some hospitals, you may have this treatment over a shorter time.
Some people might have radiotherapy after a mastectomy. This depends on the stage of the cancer.
Playing An Active Role
You play an active role in making treatment decisions by understanding your breast cancer diagnosis, your treatment options and possible side effects.
Together, you and your health care provider can choose treatments that fit your values and lifestyle.
The National Academy of Sciences released the report, Delivering High-Quality Cancer Care: Charting a New Course for a System in Crisis in 2013. Susan G. Komen® was one of 13 organizations that sponsored this study.

Medical Treatment For Breast Cancer
Breast cancer medical treatment involves a variety of therapies to kill cancer cells, stop them from growing, attack some of their specific characteristics, or decrease the chance of them returning. These treatments are also known as systemic therapies, meaning treatments using substances that travel through the bloodstream, reaching and affecting cells all over the body.
Medical treatments include:
We also offer access to medical treatment clinical trials to patients with all stages of breast cancer.

How Does Radiation Therapy Work
Radiation therapy uses special high-energy X-rays or particles to damage a cancer cells DNA. When a cancer cells DNA is damaged, it cant divide successfully and it dies.
Radiation therapy damages both healthy cells and cancer cells in the treatment area. Still, radiation affects cancer cells more than normal cells. Cancer cells grow and divide faster than healthy cells and also are less organized. Because of this, it’s harder for cancer cells to repair the damage done by radiation. So cancer cells are more easily destroyed by radiation, while healthy cells are better able to repair themselves and survive the treatment.
The treatment area may include the breast area, the lymph nodes, or another part of the body if the cancer has spread.
Radiation treatments are carefully planned to make sure you receive the greatest benefits and the fewest side effects possible.
- Brachytherapy/Internal Radiation
- Internal radiation, called brachytherapy by doctors, uses a radioactive substance sealed in seeds or tiny tubes that are placed inside your body directly into the cancer or the place where the cancer was. Read about brachytherapy.
Another type of radiation therapy, called intraoperative radiation therapy, is a type of partial-breast radiation. With intraoperative radiation therapy, the entire course of radiation is delivered at one time during breast cancer surgery. Read more about intraoperative radiation therapy.
Staying On Track With Radiation Treatments
The benefits of radiation therapy strongly depend on getting the full recommended dose without significant breaks, because:
- The full dose of radiation is needed to get rid of any cancer cells remaining after surgery.
- Radiation therapy is most effective when given continuously on schedule. In the past, it was given every day, 5 days a week, for 5 to 7 weeks. Accelerated, also called hypofractionated, radiation therapy schedules deliver about the same total dose of radiation over a shorter schedule usually 3 to 4 weeks, which can be more convenient. Partial breast radiation can be completed in 1 to 3 weeks. Also, by seeing your doctor regularly during and after treatment, you can best deal with any side effects.
Why you might have problems sticking to your radiation therapy plan:
- The treatment schedule may conflict with job demands, family needs, or the distance you live from the treatment facility. This may cause you to miss or postpone appointments, even if youre on an accelerated schedule.
- Skin irritation from radiation can cause soreness, peeling, and sometimes blisters. If you’ve also had lymph-node surgery, radiation treatment may worsen breast or underarm pain or discomfort. If you have these side effects, you might feel like stopping radiation.

Radiation Therapy Side Effects
The side effects of radiation therapy depend on the type of radiation therapy youre having. In general, the side effects tend to develop as treatment goes on and may be more troubling toward the end of treatment. Overall, the most common side effects are redness, swelling, and skin peeling in the area being treated. Read more about radiation therapy side effects.
In Vivo Effects Of Topical Application Of Iodine On Expression Of Estrogen
To investigate the in vivo effect and to imitate the clinical observation, we determined the effect of topical application of iodine on the established MCF-7 tumor in ovariectomized athymic nude mice. We first analyzed the effect of topical application of Iodine Tincture on iodine absorption and on estrogen-regulated genes in MCF-7 tumor. Topical application of Iodine Tincture increased urine levels of iodine, suggesting an efficient skin absorption in nude mice . Although pS2 expression on both iodine and estrogen treated groups show no significant difference compared to control levels , expression levels of CyclinD1 and Cat-D was significantly higher in the iodine or estrogen treated nude mouse when compared with the average expression levels of control group . These data suggest that skin-absorbed iodine has an estrogenic effects on MCF-7 tumors grown in athymic nude mice.

Breast Reconstruction After Surgery
Many woman having surgery for breast cancer might have the option of breast reconstruction. A woman having a mastectomy might want to consider having the breast mound rebuilt to restore the breasts appearance after surgery. In some breast-conserving surgeries, a woman may consider having fat grafted into the affected breast to correct any dimples left from the surgery. The options will depend on each womans situation.
There are several types of reconstructive surgery, but your options depend on your medical situation and personal preferences. You may have a choice between having breast reconstruction at the same time as the breast cancer surgery or at a later time .
If you are thinking about having reconstructive surgery, its a good idea to discuss it with your breast surgeon and a plastic surgeon before your mastectomy or BCS. This gives the surgical team time to plan out the treatment options that might be best for you, even if you wait and have the reconstructive surgery later.
To learn about different breast reconstruction options, see Breast Reconstruction Surgery.
Advances In Conventional Breast Cancer Treatment
Early-stage, localized breast cancer is highly treatable, but not everyone is aware that cancer treatment in general has evolved and improved in the last few years. Advances in breast cancer treatment have improved patient outcomes while also reducing side effects patients may experience during treatment. Below are a few of the most promising developments.

Symptoms Of Mammary Cancer
Breast cancer in cats is usually first characterized by lumps or nodules in the breast tissue. After the cancer has progressed more, you may notice additional symptoms.
The first sign of mammary cancer in cats is lumps or nodules in the breast tissue. You might be stroking your cat or watching them roll around on the floor, and notice a lump on their underside.
Often these lumps feel like peas or marbles under the skin, but they arent always as neat as this and can be varying shapes and textures. The lump may ulcerate, leading to blood, wounds or discharge from the undercarriage. The nipples may also swell and discharge.
Depending on how far the breast cancer has progressed you may notice pain, fever, and inappetence. If the tumor has spread to the chest, you may notice a cough.
Iodine And Companion Nutrients
Vitamins and minerals work together in the body. Iodine has several companion nutrients that must be present in the body to ensure that the full benefit of iodine is experienced. Additionally, without the companion nutrients, a reaction to iodine or lack of success with iodine supplementation is likely.

Here’s How To Cure Breast Lumps Without Surgery
Finding a lump in your breast can indeed be shocking and scary. While malignant tumors need to be removed surgically, not all of the tumors are cancerous or life-threatening.
Have you heard of ‘fibroadenoma’? They are usually lumps about 1 cm to 2 cm in size and don’t cause any pain, and can be felt like a small marble underneath the skin, on the side of the breast. But they may still require some sort of treatment.
Fibroadenomas, or these benign lumps, are usually found in young women of child-bearing age. They generally shrink or disappear without any particular treatment after menopause.
Although the reasons behind the formation of these lumps are not clearly known, researchers attribute it to estrogen dominance. Use of oral contraceptives, hormonal imbalances, and certain stimulating foods are also considered to be the cause.
During pregnancy, or hormone replacement, fibroadenomas grow quickly, but they disappear following menopause.
It is believed that natural remedies and lifestyle modifications can go a long way in preventing the occurrence of these breast lumps, and also in reducing the size of the lumps so formed. As all of these are natural and can be easily adopted by one and all, they are devoid of side-effects too.
What Is The Prognosis After Recurrence
Many patients with a recurrence of breast cancer can be successfully treated, often with methods other than radiation if radiation was used in the initial treatment. For patients treated initially for invasive breast cancer, five percent to 10 percent will be found to have distant metastases at the time of discovery of the breast recurrence. The same proportion will have recurrences that are too extensive to be operated on. While in these cases the patient’s disease can often be managed over a period of years, the goals of treatment change from obtaining a cure to preventing further progression or managing symptoms. Five-year cure rates for patients with relapse after breast conservation therapy are approximately 60 percent to 75 percent if the relapse is confined to the breast and a mastectomy is then performed.
For patients treated initially for DCIS, about one-half of recurrences are invasive and one-half noninvasive DCIS. Long-term control rates following recurrence after initial breast conservation therapy have been high, often over 90 percent.

Number And Origin Of Patients And Controls
Tables 3A, 3B show the key aggregated data for each of the nine centers and 10 databases included in our survey. The cohorts comprised altogether 7,565 female DTC survivors given RAI or not given RAI . The number of RAI patients per institution varied considerably from 15 to 1,644 and the number of controls from 0 to 419.
Table 3A. Registry survey: RAI patient and control cohort characteristics by center young age groups.
Table 3B. Registry survey: RAI patient and control cohort characteristics by center all age groups.
The three largest groups of RAI patients, with more than 1,000 cases each, were contributed by the participating centers in Münster, Kiev, and Pisa. By contrast, by far the largest no RAI control group was provided by the Foundation ARNICA, Minsk, with a total of more than 500 controls . Table 3A is firstly a list of the three cohorts from Minsk and Kiev, which included a considerable proportion of young patients who developed DTC after the Chernobyl reactor accident in 1986 .
Vitamins To Avoid During Radiation Therapy
Your radiation oncologist may tell you to avoid taking certain antioxidant vitamin supplements, such as vitamins C, A, D, and E, while you’re having radiation therapy. These vitamins might interfere with radiation’s ability to destroy cancer cells.This is because radiation works in part by creating free radicals highly energized molecules that damage cancer cells. Free radicals in the environment can damage all cells, but in the case of radiation treatment they are focused on the cancer cells. Antioxidants help keep free radicals from forming or neutralize them if they do form.
Because of the potential conflict between the goal of radiation therapy and the goal of antioxidants , it makes sense to stop taking any antioxidant supplements during radiation therapy. When radiation is finished, you can resume taking your supplements.
Throughout your treatment, do your best to eat a well-balanced diet that contains all of the vitamins you need. Vitamins that come naturally from food are unlikely to interfere with treatment.

What Are The Chances Of Breast Cancer Recurrence After Treatment For Stage 2 Breast Cancer
In women who have breast-conserving treatment, the chance of recurrence is about 3-15% in 10 years, depending on tumor characteristics and margins. Distant recurrence in those who had mastectomy is most influenced by axillary lymph node involvement. When axillary lymph nodes are not cancerous, the recurrence rate is 6% in 5 years. When axillary lymph nodes are cancerous, the recurrence rate is 23% in 5 years with mastectomy but no radiation.
Cancer Treatment Premature Menopause And Infertility
About a quarter of the nearly 285,000 women diagnosed with breast cancer in the U.S. each year have not gone through menopause.
Some chemotherapy and hormone therapy drugs that treat breast cancer can cause permanent or temporary infertility or early menopause. Women who havenât yet gone through menopause should use birth control while having these treatments, because some chemotherapy drugs are linked with birth defects.
Chemotherapy-induced menopause happens in 10% to 50% of women younger than 40 and in 50% to 94% of women over 40. After chemotherapy, you may have months or even years of uneven ovarian function.
Radiation therapy wonât cause infertility unless it is directed at both ovaries. Depending on the type and extent of the breast cancer, your ovaries may be surgically removed or radiated to lower the amount of estrogen that your body makes. This will cause permanent infertility.
Women with breast cancer who want to start or expand a family later on should consider options to keep fertility before beginning treatment. These include:

When Is Radiation Usually Used To Treat Stage 2 Breast Cancer
According to the American Cancer Society, radiation therapy may be used after lumpectomy to mitigate the risk of cancer cells recurring in the same breast or nearby lymph nodes. After a mastectomy, an oncologist may determine that radiation is necessary if the tumor was larger than 5 cm, if there was lymph node involvement, or if cancer was found outside of surgical margins.
What Is Breast Cancer In Cats
Cats have around four pairs of teats in each mammary chain, or eight mammary glands, although this can vary. Feline mammary tumors, aka cat breast cancer, are tumors of one or more of the mammary glands.
It is more common to have the tumors in the first pair of glands or the last pair . They are more common in females than males and are also more common in un-spayed cats. Some sources claim theyre the third most common feline tumor, after lymphoma and skin cancer.
Cats are more likely to get breast cancer if theyre intact/entire, female, and 10+ years old, although cases in cats as young as 4 years have been recorded.
Siamese cats have twice the risk of tumors as mixed-breed cats, and other oriental breeds also get breast cancer more commonly. Whilst it is possible for male cats to get mammary gland tumors, it is less common than for females.

Local Or Regional Treatments For Stage Iv Breast Cancer
Although systemic drugs are the main treatment for stage IV breast cancer, local and regional treatments such as surgery, radiation therapy, or regional chemotherapy are sometimes used as well. These can help treat breast cancer in a specific part of the body, but they are very unlikely to get rid of all of the cancer. These treatments are more likely to be used to help prevent or treat symptoms or complications from the cancer.
Radiation therapy and/or surgery may also be used in certain situations, such as:
- When the breast tumor is causing an open or painful wound in the breast
- To treat a small number of metastases in a certain area, such as the brain
- To help prevent or treat bone fractures
- When a cancer is pressing on the spinal cord
- To treat a blood vessel blockage in the liver
- To provide relief of pain or other symptoms anywhere in the body
In some cases, regional chemo may be useful as well.
If your doctor recommends such local or regional treatments, it is important that you understand the goalwhether it is to try to cure the cancer or to prevent or treat symptoms.
Sentinel Lymph Node Biopsy And Axillary Lymph Node Dissection
Sentinel lymph node biopsy is currently preferred for axillary staging, because it offers accuracy equivalent to that of ALND with less morbidity. The American College of Breast Surgeons states the following:
SLN biopsy is suitable for virtually all patients with clinically node-negative T1-2 invasive breast cancers
Limited data are available regarding the suitability of SLN biopsy for patients with T3 cancers, multifocal/multicentric disease, prior radiation therapy, or prior breast/axillary surgery
SLN biopsy appears to be feasible in patients who have had minimal axillary surgery the decision to use it in these situations requires individualized surgical judgment and an unequivocally successful mapping procedure
SLN biopsy is also indicated in patients with ductal carcinoma in situ in whom mastectomy is required or invasive disease is suspected
ALND is a complete en bloc removal of the level I and level II lymph nodes the level III nodes are not removed unless suspicious or palpable adenopathy is present. All nodal tissue defined by the borders of the axillary vein superiorly, the latissimus dorsi laterally, the medial border of the pectoralis minor medially, and the subscapularis posteriorly is removed.
ALND carries a high rate of surgical morbidity, including the following:
Immediate postoperative care involves the following:
Recommendations for longer-term follow-up are as follows:
