Prostheses (Prosthetics)
In cancer care, implants and prostheses (also known as prosthetics) can play a crucial role in helping people recover and maintain their quality of life.
What is a prosthesis?
A prosthesis is the general term for a device, implant, or other replacement for a body part or function. This can also include ostomy supplies, catheters, and even wigs.
Other terms to know:
- The plural of prosthesis is prostheses.
- You might also hear these called prosthetics.
- Prostheses that are surgically placed inside the body are known as implants.
Why would someone with cancer get a prosthesis?
Sometimes, a person gets a prosthesis because a part of their body is removed to treat or prevent cancer. Someone might also get a prosthesis when a body part is still there, but doesn’t look or function the same way it did before. Prostheses also are used to help manage the side effects of different types of cancer treatment.
Surgery to treat cancer
Many types of cancer surgery require removing one or more parts of the body because cancer is there. Some examples include:
- Mastectomy (one or both breasts)
- Prostatectomy (all or part of the prostate)
- Laryngectomy (all or part of the larynx — voice box)
Surgery to prevent cancer
Some people choose to have a body part removed to help prevent cancer from developing. For example, someone who is at very high risk for breast cancer might choose to have a prophylactic double mastectomy (to remove both breasts to prevent breast cancer).
Certain side effects of cancer treatment
Other types of cancer treatment can also result in side effects that change a person’s appearance. Side effects like hair loss (alopecia) can be traumatic for many people. Wigs and other hair pieces (cranial prostheses) can be used to manage hair loss.
People often choose to get prostheses to help them function -- physically or emotionally-- better. Many people find that a good prosthesis can help with both.
Types of prostheses
There are many different types of prostheses. Some are worn on the outside of the body and can be put on and taken off (such as a breast form or leg prosthetic). Others are internal and often placed surgically (such as breast or penis implants).
Many types of cancer surgery for breast cancer remove parts (lumpectomy) or all (mastectomy) of the breast tissue. Depending on how much tissue is removed, implants or prostheses may be recommended.
- Breast implants are placed inside your body, with surgery.
- A breast prosthesis (or breast form) is worn outside your body.
Whether you use a breast prosthesis or an implant will depend on the type of breast surgery you have, other cancer treatments you might need, the risks and benefits of each, and your own personal preferences.
Breast implants
- Your surgeon might place your implant during the surgery to remove your breast cancer. Or it might be placed during a separate surgery.
- Breast implants come in different shapes and sizes. They are made of either silicone gel or saline water. Many people prefer silicone implants because they feel softer and more natural.
Breast prostheses
A breast prosthesis (or breast form) is placed and worn inside a bra or other support garment. They are often made of silicone, foam, or cotton. Here are some tips when choosing and getting fitted for a breast prosthesis:
- If you’ve had a smaller portion of your breast tissue removed, small prostheses (equalizers) are available.
- Nipple prostheses can be added during surgery when the nipple can’t be saved. Breast forms are available with and without nipples.
- Wear a fitted top when you shop for a prosthesis so you can see how it looks when you move.
- Try different options. Prostheses vary in shape, weight, and consistency. Ask about custom options if needed.
- Prostheses may feel heavy, but a good prosthesis should stay in place and feel comfortable when you move. It should also look and feel like your natural shape.
- Some breast prostheses have an air pump so you can adjust the size to your preference.
To make your breast prothesis last as long as possible, follow the directions for cleaning. Body oils and sweat can wear out the materials.
Insurance coverage of breast prostheses after mastectomy
Prostheses related to a mastectomy are required to be covered by commercial insurance under the Women’s Health and Cancer Rights Act. This includes people who have prophylactic mastectomies to prevent cancer.

Some cancer treatments can cause temporary or permanent hair loss (alopecia). Wigs and certain hair pieces used for medical-induced hair loss are called cranial prostheses. This means they might be partially or fully covered by your insurance.
Ask your insurance company what documents are needed to approve your cranial prosthetic. This might include a letter or prescription from your doctor. If you’ve already paid out-of-pocket, you might be able to submit for reimbursement.
Learn about hair loss and wigs.
Certain cancers require eye removal (called enucleation). This is often part of treatment for eye cancers, such as ocular melanoma, ocular lymphoma, and retinoblastoma. In these cases, you might be offered an artificial eye (ocular prosthesis or implant).
Artificial eyes are usually made of silicone or hydroxyapatite (a bone-like material). An ocularist is a doctor who specializes in eye prostheses. They will work with you and your cancer care team to find the best option. Prosthetics can be custom-made to match your eye size and color.
It’s often difficult or impossible to tell a prosthetic apart from a natural eye. Certain surgeries allow the surgeon to attach the prosthetic eye to your eye muscles, so it even moves the same way as your natural eye did.

Treatment for head and neck cancer almost always includes some type of surgery to remove the tumor and sometimes the area around it. Many of these surgeries can change how your face looks or functions.
Reconstructive surgeries might use a prosthesis or implant to help with appearance, chewing and swallowing, speaking, or smelling. Prosthetic specialists work with your surgeon to make custom prostheses and implants based on the size and shape of the part that’s removed.

In some types of advanced cancer (like osteosarcoma) where surgery to save the limb (limb-sparing) isn’t possible, it may need to be removed. Physical and activity limits are the most significant changes most people deal with after amputation (surgery to remove part or all of a limb). Before surgery on a limb (arm, leg, foot, or hand), ask about prosthesis options, risks, benefits, and how your prosthesis will be fitted.
- Sometimes, a bone implant is attached to an external prosthesis.
- Targeted muscle reinnervation (TMR) might also be used. This is a procedure to make the prosthesis more stable and easier to control, as well as to relieve pain.
- Depending on the limb affected and how much needs to be removed, a temporary limb prosthesis might be fitted during the first surgery and a permanent prosthesis can be fitted later.
- Be sure you know how to care for the surgical site and the prosthesis.

You might choose to get a penile implant (internal) or use a penile prosthesis (external) after surgery for penile or prostate cancer, or if other cancers or cancer treatments affect your ability to have an erection.
- Penile prostheses are external and worn outside the body. They are often attached with a strap.
- Penile implants are internal. They are placed after recovery from cancer surgery.
- You might want to discuss the possibility of a prosthesis or implant with your partner.
- Counseling sessions could help you make a decision.
- Different types, sizes, and shapes of penile prostheses and implants are available. Talk to your cancer care team and your partner about your options and the best type for you.
- Talk to your insurance company about coverage.

The main treatment for testicular cancer is surgery to remove the testicle with cancer (orchiectomy). A testicular implant can be placed in the scrotum either during the orchiectomy or in a separate surgery. Before surgery, talk to your cancer care team about whether you want a testicular implant.

Living with a prosthesis
Depending on the type of prosthesis, you might have follow-up care and appointments. It’s important to tell your health care team how you’re doing with your prosthesis. This includes any problems, concerns, or questions you might have.
Sometimes, rehabilitation (rehab) or therapy is recommended for people with cancer who are learning to live with a new prosthesis. Rehab and therapy (physical, occupational, or speech ) can improve your function, comfort, and quality of life.
Cancer rehab is a supportive health care program that can help if you have physical or mental side effects caused by cancer or cancer treatment. This includes learning how to resume daily activities with your new prosthesis. It also includes learning how to cope with both the physical and emotional effects of living with a prosthesis.

Does insurance cover prosthetics for cancer?
Many insurance plans cover some or all of the cost of a prosthesis.
The Affordable Care Act (ACA) requires all small group insurance plans to cover essential benefits, including prosthetics. But in reality, insurance coverage varies depending on what insurance plan you have and what prostheses you need.
If and how much of the cost is covered often depends on whether the prosthesis is considered “medically necessary.” There isn’t a standard definition of what is medically necessary, so coverage varies among insurance providers.
Medicare Part B
Most prosthetics that replace a body part or function are covered under Medicare Part B as Durable Medical Equipment (DME). However, if they aren’t considered medically necessary, they might not be covered. For example, Medicare doesn’t consider cranial prostheses (wigs) for hair loss to be medically necessary.
Maximizing insurance coverage for your prosthesis
If you are looking into insurance coverage for a prosthesis, there are a few ways you can increase your chances of being approved and getting the maximum benefit possible.
Talk to an insurance representative beforehand
It's a good idea to talk to someone at your insurance company before you get your prosthesis. Knowing certain information ahead of time can speed up the process and help you get the most from your benefits.
Here are some questions to ask your insurance provider:
- Do you require pre-authorization or pre-approval?
- What information or documentation do you need for approval?
- Is there any specific terminology the doctor should include?
- If approved, how much do you cover?
- Do you cover a certain number of prostheses or supplies per year or lifetime?
- Are there any restrictions about the type of prosthesis I can get? (For example, Medicare plans only cover prosthetics and supplies from a Medicare-enrolled supplier.)
Check your current policy status
Consider any remaining deductibles, coinsurance, and coverage limitations or caps. These can increase or decrease your final out-of-pocket expenses.
Learn more about managing insurance and cancer-related expenses.
Communicate with a prosthetist
If you’re working with a prosthetist (prostheses specialist), give them as much information as possible about your insurance coverage. They might be able to recommend certain prosthetics that meet your needs while keeping your out-of-pocket costs as low as possible.
Your cancer care team can help give recommendations for locating a prosthetist if one is not available to you through your cancer or rehabilitation center. The Amputee Coalition also offers an online directory of member prosthetists to help you in your search.
