Mastectomy is a surgical procedure to remove all or part of the breast tissue to treat or prevent breast cancer. While mastectomy typically involves the removal of the entire breast, in some cases, it may also involve the removal of other tissues near the breast, such as the lymph nodes and chest wall muscles. The decision to undergo a mastectomy is a personal one and can evoke various emotions. Patients opting for mastectomy may simultaneously undergo breast reconstruction surgery, which can be immediate or staged.

What You'll Learn
Mastectomy removes the entire breast
A mastectomy is a surgical procedure to remove the entire breast, including the nipple, areola, and sometimes the overlying skin. It is a treatment for breast cancer, with the aim of removing cancerous cells and preventing the cancer from spreading to other parts of the body.
There are several types of mastectomies, depending on the extent of tissue removal and the surgical approach. In a simple mastectomy, only the breast tissue, nipple, and areola are excised, leaving most of the skin intact. This type of mastectomy is often chosen for smaller tumors or those located deeper within the breast. On the other hand, a modified radical mastectomy involves removing the entire breast, along with the lymph nodes under the arm (axillary lymph node dissection). The pectoral muscles under the breast may also be removed in some cases, especially if the cancer has spread to these muscles or as a preventive measure if there is a high risk of recurrence.
The decision to undergo a mastectomy is deeply personal and can evoke various emotions. Patients may feel anxious about removing the tumor while also experiencing grief and a sense of losing part of their identity. It is essential for patients to thoroughly discuss the procedure with their healthcare providers, understand the risks and benefits, and explore the different options for breast reconstruction, which can be done simultaneously or through a staged process.
Mastectomies are typically recommended when certain conditions are met. For instance, if cancer cells are found at the margins of the previously removed tissue, if there is a local recurrence after breast-conserving surgery, or if the patient has a large lump (tumor) in a small breast. Additionally, patients with a high risk of developing breast cancer, such as those with a BRCA gene mutation or a strong family history of breast cancer, may opt for a mastectomy as a preventive measure.

It is a treatment for breast cancer
A mastectomy is a surgical procedure to remove the entire breast, including the nipple, areola, and sometimes the overlying skin. It is a treatment for breast cancer, aimed at removing the cancerous tissue and preventing its spread. The procedure can be performed on one or both breasts, depending on the patient's situation and the extent of the cancer.
During a mastectomy, the surgeon removes the breast tissue, nipple, and areola. In some cases, the skin over the breast is preserved, while in other instances, it may be removed along with the underlying chest muscles and lymph nodes. The decision to remove additional tissues depends on the location and stage of the cancer.
There are several types of mastectomies, including:
- Simple mastectomy: This involves the removal of the entire breast, including the nipple and areola, but the skin over the breast is left intact.
- Modified radical mastectomy: This procedure combines a simple mastectomy with the removal of lymph nodes under the arm (axillary lymph node dissection). While this extensive surgery was commonly performed in the past, less extensive alternatives, such as the modified radical mastectomy, are now preferred due to their comparable effectiveness and reduced side effects.
- Radical mastectomy: This involves the removal of the entire breast, along with the nipple, areola, overlying skin, lymph nodes under the arm, and the chest muscles under the breast. This type of mastectomy was once the standard surgery for breast cancer but is now rarely performed.
- Skin-sparing mastectomy: This approach removes the breast tissue, nipple, and areola while preserving most of the skin over the breast. It is often chosen for its advantage of less scar tissue and a more natural-looking reconstructed breast. However, it may not be suitable for larger tumors or those close to the skin surface.
- Nipple-sparing mastectomy: Similar to the skin-sparing mastectomy, this procedure removes all breast tissue, including the ducts leading to the nipple and areola, while preserving the skin and nipple.
After a mastectomy, patients may choose to undergo breast reconstruction surgery to restore the appearance of the breast. This can be done immediately after the mastectomy or at a later time. Reconstruction can be achieved through implants, tissue from other parts of the body, or a combination of both.
Mastectomies are a crucial treatment option for breast cancer, offering a chance to remove the cancerous tissue and prevent its recurrence. However, it is important to carefully consider the advantages and disadvantages of different mastectomy types and make an informed decision in consultation with a skilled medical team.

There are different types of mastectomies
A mastectomy is a surgery to remove the entire breast, usually as a treatment for breast cancer. However, it can also be done preventively for patients with a high risk of developing breast cancer, such as those with a BRCA gene mutation. The procedure involves removing the breast tissue, nipple, areola, and sometimes the overlying skin and lymph nodes.
There are several different types of mastectomies, depending on the specific tissues removed and the extent of the surgery. Here are some of the most common types:
- Simple Mastectomy: This type of mastectomy involves removing the entire breast, including the nipple, areola, and most of the overlying skin. It is called a "simple" mastectomy because it does not involve the removal of additional tissues or muscles.
- Skin-sparing Mastectomy: During this procedure, the breast tissue, nipple, and areola are removed, while most of the skin over the breast is preserved. This type of mastectomy is often chosen because it results in less scar tissue and allows for a more natural-looking breast reconstruction. However, it may not be suitable for larger tumors or those close to the skin surface.
- Nipple-sparing Mastectomy: This is similar to the skin-sparing mastectomy, as it involves removing all the breast tissue, ducts, and lymph nodes while preserving the skin of the nipple and areola. The tissues around these areas are carefully examined by a pathologist to ensure no cancer cells are present.
- Modified Radical Mastectomy: This procedure combines a simple mastectomy with the removal of the lymph nodes under the arm (axillary lymph node dissection). While this extensive surgery was once common, less extensive options have been found to be equally effective with fewer side effects.
- Radical Mastectomy: This type of mastectomy involves removing the entire breast, including the nipple, areola, overlying skin, lymph nodes under the arm, and the chest muscles under the breast. It is typically advised when breast cancer has spread to the chest muscles or in cases with a strong family history of breast cancer or a cancer gene mutation.
- Double or Bilateral Mastectomy: This involves the removal of both breasts and can be done as a risk-reducing or preventive measure for women at a very high risk of developing breast cancer.
It is important to note that the choice of mastectomy type depends on various factors, including the size and location of the tumor, the patient's preferences, and the surgeon's recommendations. In some cases, breast reconstruction surgery can be performed simultaneously or as a subsequent procedure to restore the breast's size and shape.

Mastectomy can be done to prevent breast cancer
A mastectomy is a surgical procedure to remove the entire breast. It is a treatment for breast cancer. During the procedure, the surgeon removes the breast tissue, nipple, and areola. In some cases, the skin overlying the breast and the lining over the chest muscles are also removed.
Mastectomies can be unilateral or bilateral, meaning that either one or both breasts are removed, respectively. The type of mastectomy performed depends on the patient's situation and surgeon recommendation. For example, a mastectomy may be recommended if a patient has a large lump (tumor) in a small breast.
Mastectomies can also be performed as a preventive measure for patients with a high risk of developing breast cancer. This includes patients with a harmful mutation in a breast cancer susceptibility gene, such as BRCA1, BRCA2, TP53, or PTEN. Preventive mastectomies are also known as prophylactic mastectomies and can lower breast cancer risk by 90% or more. However, it is important to note that a mastectomy does not guarantee that a patient will not develop breast cancer.
In addition to the removal of the breast, the surgeon may also remove some of the lymph nodes under the arm (axillary lymph node dissection). This is because breast cancer often spreads to these lymph nodes and then to other parts of the body. The surgeon may also recommend breast reconstruction surgery during the same procedure. This can be done using implants or tissue from other parts of the body.

Breast reconstruction surgery is an option post-mastectomy
A mastectomy is a surgery to remove the entire breast, including the nipple, areola, and fascia (covering) of the pectoralis major muscle (main chest muscle). In some cases, a modified radical mastectomy is performed, which involves removing the breast, axillary (underarm) lymph nodes, and the pectoral (chest wall) muscles under the breast. This type of surgery was once common but is now rarely done due to less extensive and equally effective alternatives.
Breast reconstruction surgery is an option for individuals who have undergone a mastectomy. This procedure aims to recreate the shape of the breast using implants, autologous tissue (tissue from the patient's body), or a combination of both. Breast reconstruction can be performed immediately after a mastectomy or delayed until months or years later. The timing depends on various factors, including the patient's health condition, personal preference, and the need for additional treatments such as radiation therapy.
Immediate breast reconstruction offers the advantage of waking up with the initial stages of breast reconstruction already completed. However, it can be challenging to consider reconstruction options during an already stressful time before cancer surgery. Additionally, if cancer recurs, the reconstruction may need to be modified, and postsurgical complications could require further surgeries.
Delayed breast reconstruction allows patients to focus on their recovery from mastectomy and any subsequent treatments without the added complexity of immediate reconstruction. It also enables patients to make more thoughtful decisions about their reconstruction options without feeling rushed. Delayed reconstruction can be performed months or even years after the mastectomy, giving patients flexibility in their treatment journey.
The decision to undergo breast reconstruction is deeply personal, and not everyone chooses to have it. Some individuals may opt for a flat closure, also known as "going flat," where the surgeon removes excess skin, fat, and tissue in the breast area to create a smooth and contoured chest wall. Others may choose to use external breast prostheses or breast forms to achieve the appearance of breasts without surgical reconstruction.
