A mastectomy is a surgical procedure to remove one or both breasts, which is most often done to treat or prevent breast cancer. The surgery may also involve the removal of other tissues near the breast, such as the nipple, areola, lymph nodes, and chest muscles. The type of mastectomy performed depends on the patient's diagnosis and can range from a simple mastectomy to a modified radical mastectomy, which includes the removal of lymph nodes and chest muscles. Breast reconstruction surgery is often done simultaneously with a mastectomy to create a new breast shape using implants or tissue from other parts of the body.

Types of mastectomy
A mastectomy is a surgery to remove a breast, usually as a treatment for breast cancer. The surgery can involve the removal of the nipple, areola, and some overlying skin. In some cases, lymph nodes in the armpit may also be removed.
There are several types of mastectomies, depending on how the surgery is performed and how much tissue is removed. Here are some of the most common types:
Simple Mastectomy
This procedure involves the removal of the entire breast, including the nipple, areola, and most of the overlying skin. It is also known as a total mastectomy. This type of mastectomy is often performed when the tumour is large or located near the skin surface.
Modified Radical Mastectomy
The modified radical mastectomy combines a simple mastectomy with the removal of the lymph nodes under the arm (axillary lymph node dissection). This extensive surgery used to be very common but is rarely performed now. Instead, less extensive surgeries, such as the modified radical mastectomy, are preferred as they have been found to be equally effective with fewer side effects.
Radical Mastectomy
A radical mastectomy involves the removal of all breast tissue, including the nipple, areola, axillary lymph nodes, and skin. Additionally, the chest wall muscles under the breast are also removed. This type of mastectomy is typically performed when breast cancer has spread to the muscle beneath the breast or in cases where there is a strong family history of breast cancer or a cancer gene mutation.
Skin-Sparing Mastectomy
During a skin-sparing mastectomy, the breast tissue, nipple, and areola are removed, while most of the skin over the breast is preserved. This type of surgery is often chosen when breast reconstruction is planned right after the mastectomy. It may not be suitable for larger tumours or those close to the skin surface.
Nipple-Sparing Mastectomy
A nipple-sparing mastectomy is similar to a skin-sparing mastectomy, as it involves the removal of all breast tissue, ducts, and lymph nodes, while preserving the skin of the nipple and areola. This procedure is only recommended if no cancer cells are found close to the nipple and areola.
It is important to note that the choice of mastectomy type depends on various factors, including the size and location of the tumour, the patient's breast size, and their personal preferences. Breast reconstruction surgery can be performed simultaneously or as a separate procedure to restore the size and shape of the breast.

Breast reconstruction
Mastectomy is a procedure to remove the entire breast as a treatment for breast cancer. In some cases, a mastectomy is done to help prevent breast cancer in women who are at high risk of developing it. The surgery may also involve the removal of the nipple, areola, and some underarm lymph nodes.
There are two main types of breast reconstruction surgery: implant-based reconstruction and flap reconstruction. Implant-based reconstruction uses breast implants to form a new breast mound. Flap reconstruction, also known as autologous reconstruction, uses the patient's own tissue from other parts of the body, such as the lower abdomen, thigh, back, or bottom.

Preventing breast cancer
Mastectomy is a surgical procedure to remove the entire breast as a treatment for breast cancer. While a mastectomy is not a sure way to prevent breast cancer, it can be used as a preventive measure for women at high risk of developing the disease. Women with a BRCA1 or BRCA2 gene mutation, for instance, may opt for a mastectomy to reduce their risk.
For those who do not want to undergo surgery, there are other ways to lower the risk of breast cancer. Maintaining a healthy weight and engaging in regular physical activity are recommended by the American Cancer Society to reduce the risk of developing breast cancer. The Society suggests that adults engage in at least 150 to 300 minutes of moderate-intensity exercise or 75 to 150 minutes of vigorous-intensity activity each week.
Additionally, certain prescription drugs, such as tamoxifen and raloxifene, can significantly lower the risk of breast cancer in women at high risk. However, these drugs are not suitable for everyone due to potential side effects, so it is important to consult a doctor before taking them.
Another option for women who do not want to undergo surgery or take medication is to undergo frequent screening and monitoring. This may include more frequent doctor visits, yearly mammograms, and additional screening tests such as breast MRI. While this approach does not lower the risk of breast cancer, it can help detect it in its early stages when treatment is more likely to be successful.

Removing lymph nodes
A mastectomy is a surgery to remove the entire breast, including the nipple, areola, and sometimes the overlying skin. It is a treatment for breast cancer, and in some cases, it is done as a preventive measure for those at high risk of developing the disease. The procedure may also involve the removal of some nearby tissues, such as the lymph nodes and chest muscles.
Lymph nodes are small, bean-shaped structures located throughout the body. They play a crucial role in the lymphatic system, which is responsible for filtering out waste, bacteria, and other harmful substances. During a mastectomy, a few underarm lymph nodes may be removed as part of a sentinel lymph node biopsy or an axillary lymph node dissection. This is done to determine whether cancer has spread beyond the breast.
The sentinel lymph node is the first node "downstream" from the cancer in the lymph circulatory system. It is the node that cancer cells are most likely to spread to first if they travel away from the breast tumor and into the lymphatic system. By removing and examining this node, doctors can assess whether the cancer has spread and make informed decisions about further treatment.
In some cases, a more extensive surgery called a modified radical mastectomy may be performed. This procedure involves the removal of the entire breast, the axillary (underarm) lymph nodes, and the pectoral (chest wall) muscles under the breast. However, this type of surgery is rarely done today, as less extensive procedures have been found to be equally effective with fewer side effects.
After lymph node surgery, patients may experience side effects such as pain, swelling, bleeding, blood clots, and infection. A possible long-term effect is lymphedema, which is a chronic condition caused by a disruption to the normal drainage pattern in the lymph nodes. It typically causes swelling in the arm but can also affect the breast, chest, and legs.

Post-mastectomy recovery
A mastectomy is a procedure to remove one or both breasts, usually performed to treat or prevent breast cancer. The recovery time for a mastectomy is typically around 3 to 4 weeks, but this can vary depending on the type of mastectomy performed and the individual's health condition.
During the procedure, the surgeon may remove the entire breast, including the nipple, areola, skin, and sometimes the lymph nodes and chest wall muscles under the breast. In some cases, a mastectomy may be performed with immediate breast reconstruction, where tissue from other parts of the body or implants are used to reconstruct the breast. This can result in a feeling of tightness or pressure in the chest area.
Post-mastectomy, patients may experience some side effects and will require time to heal. It is common to experience numbness in the surrounding tissues as surgeons inject a significant amount of numbing medication during the procedure. Over-the-counter pain relievers are usually sufficient to manage any pain or discomfort. Patients may also develop post-mastectomy pain syndrome, a type of nerve pain that can occur in the chest wall, inner arm, and armpit.
It is recommended to wear a mastectomy bra designed to accommodate drains that may be in place. Soft sports bras can also be worn when the mastectomy bra is being laundered. Patients should also consider their wardrobe choices post-surgery, as they may have difficulty with pullover clothing or tying their shoes. Planning ahead for accessibility by keeping frequently used items within easy reach at waist level can be helpful.
Overall, the recovery process for a mastectomy typically takes a few weeks, and patients can expect to gradually return to their usual activities. However, it is important to follow the surgeon's advice and guidelines for a safe and effective recovery.

Frequently asked questions
A mastectomy is surgery to remove one or both breasts, which is done to treat or prevent breast cancer.
There are several types of mastectomies, and some remove more tissue than others. A radical mastectomy removes all breast tissue, underarm lymph nodes, and the pectoral muscles underneath. This type of mastectomy is rare these days but may be necessary if the cancer has spread to the muscles.
The different types of mastectomies include the simple mastectomy, modified radical mastectomy, nipple-sparing mastectomy, skin-sparing mastectomy, and double or bilateral mastectomy.
A mastectomy is performed under general anesthesia. The surgeon removes all the breast tissue, and in most cases, the nipple and areola are also removed. The surgeon closes the skin with stitches and puts in surgical drains to allow extra fluid to drain out.
After a mastectomy, you will experience some soreness and numbness in your chest, underarm, and shoulder. This numbness is usually permanent, although you may regain some feeling over time. You may also experience reduced range of motion in your shoulder, and your activities will be restricted during recovery.
