Breast cancer survivorship in older adults

Overview

Breast cancer survivorship means living life after breast cancer treatment. For older adults, this includes regular checkups, managing any long-term side effects of treatment, and focusing on physical and emotional wellbeing. It is not just about surviving the cancer — it is about thriving in your later years.

Yes. Breast cancer is the most common cancer among women worldwide, and many people who are treated for it are over the age of 65. As the population ages, the number of older breast cancer survivors is growing.

It mainly affects women over 65 who have been treated for breast cancer, but it can also affect men. Older adults with a previous breast cancer diagnosis are considered survivors, whether they finished treatment recently or many years ago.

Symptoms

Common symptoms

• Ongoing fatigue or tiredness
• Swelling of the arm, hand, or breast area (called lymphoedema)
• Mild pain or discomfort where the cancer was or where surgery was done
• Changes in memory, concentration, or 'brain fog'
• Sleep problems
• Anxiety or worry about the cancer coming back

Symptoms in children

• Not applicable. This topic is about breast cancer survivors, who are typically adults.

Symptoms in older adults

• Weakness or difficulty with daily tasks that used to be easy
• Joint or bone pain, especially if you had hormone therapy
• New or worsening swelling in an arm or leg
• Feeling unusually tired after minimal activity
• Changes in appetite or weight without a clear reason

Causes

Main causes

• The natural effects of cancer treatment on the body, such as surgery, radiation, and hormone therapy
• Long-term physical changes that can show up after treatment ends
• Emotional effects of going through cancer, such as stress and worry
• Ageing itself, which can make the body slower to recover or adjust

Risk factors

• Being over the age of 65 at the time of treatment
• Having had radiation therapy to the chest area
• Having had certain types of chemotherapy or hormone therapy
• Having other long-term health conditions like heart disease, diabetes, or arthritis
• Not attending regular follow-up appointments
• Living alone or having limited social support

When to see a doctor

See a doctor urgently if:

• If you have any of the emergency symptoms listed above, call your local emergency number immediately.
• If you have new, severe pain, sudden swelling, fever, or a wound that looks infected, see a doctor the same day.

Book a routine appointment if:

• Attend all scheduled follow-up appointments with your cancer care team.
• Tell your doctor about any new symptom that lasts more than two weeks, even if it seems minor.
• Bring a list of your current medicines and any questions you have.

Diagnosis

Survivorship is not diagnosed like a new disease. Instead, your doctor will review your cancer history, ask about your current symptoms, and run tests to check for signs of recurrence or late effects of treatment. This is usually called a survivorship assessment.

Tests that may be done

• A physical exam of your breasts, chest, arms, and lymph nodes
• Regular mammograms to screen for recurrence in the breast or chest area
• Bone density scanning (DEXA scan) to check bone strength, especially if you had hormone therapy
• Blood tests to check organ function or detect markers of concern
• Imaging tests like ultrasound, CT scan, or MRI only if your doctor thinks they are needed

What to expect at your appointment

Your doctor will sit down with you, listen to your concerns, and do a gentle exam. The tests are usually painless and often take only a few minutes. You will get clear results and be told what to watch for. If anything is unclear, you can ask for more time and explanation.

Treatment

In survivorship, treatment focuses on preventing recurrence, managing long-term side effects, and keeping you independent and comfortable. It is a team effort — your doctor, nurses, and you work together to make a plan that suits your life and preferences.

Self-care at home

• Keep a simple record of any new symptoms and share it with your care team
• Wear compression sleeves or garments if recommended for swelling in the arm
• Protect your affected arm from cuts, burns, or tight jewellery to reduce swelling risk
• Stay active at a level that feels good, like short walks or gentle stretching
• Rest before you feel exhausted, and pace your daily activities

Medical treatments

Medical treatment in survivorship may include physical therapy to help with swelling or mobility, occupational therapy to support daily tasks, and medications to manage specific issues like bone thinning, pain, or infection. Hormone therapy may be continued for several years after the initial treatment to lower the risk of recurrence. Your doctor will explain the possible benefits and side effects of any treatment and will only recommend something that fits your overall health.

When is surgery considered?

In some cases, further surgery may be suggested to improve comfort or address complications, such as reducing fluid buildup, improving breast appearance after mastectomy, or replacing implanted devices. This is always discussed carefully, and you have time to think and ask questions.

Living with this condition

Living with survivorship means finding a new rhythm. Some days are easier than others. Keep your morning routine simple, prioritise rest, ask for help when you need it, and allow yourself to enjoy the moments that bring you joy. A predictable daily structure can reduce anxiety and help you feel more in control.

Lifestyle tips

• Stay active in a way you enjoy — walking, gardening, or gentle exercise are all good
• Limit alcohol and avoid smoking to reduce cancer risk
• Keep up with social connections — even a phone call can lift your mood
• Practice good sleep habits, like a set bedtime and limiting screens in the evening
• Keep your mind active with reading, puzzles, or hobbies

Diet and exercise

Eat a varied diet with plenty of fruits, vegetables, whole grains, and protein from beans, fish, or lean meats. Go easy on processed foods and sugary drinks. For exercise, aim to move a little every day — even 10 minutes of walking can help. If you are unsure what is safe, ask your doctor or a physiotherapist to suggest gentle exercises that keep your joints flexible and your muscles strong.

Mental health and emotional wellbeing

It is very common to feel anxious, low, or afraid after cancer treatment. You may worry about every new ache or pain. These feelings are real and normal. Talking to a counsellor, joining a support group, or simply sharing your worries with a trusted friend or family member can make a big difference. You do not have to go through this alone.

Prevention

You cannot fully prevent the cancer from coming back, but you can lower your risk by following your follow-up plan, staying active, eating well, keeping a healthy weight, and managing other health conditions like diabetes or high blood pressure. A healthy lifestyle also improves your energy and mood.

Vaccines

Staying up to date with recommended vaccines, such as the flu vaccine and a pneumonia vaccine, is a sensible part of staying healthy. Ask your doctor or pharmacist which vaccines they recommend for your age and health.

Screening programmes

Yes. Regular mammograms and bone density scans are an important part of survivorship care. Your doctor will tell you how often you need them. Do not skip these tests — they can catch problems early, when they are easier to treat.

Complications

If left untreated

• Lymphoedema that becomes worse and can limit arm movement or cause skin infections
• Loss of muscle strength and balance, which may increase the risk of falls
• Bone thinning (osteoporosis) and a higher chance of fractures
• Undetected recurrence, which may be harder to treat if found later
• Unmanaged anxiety or depression, which affects quality of life and physical health

Long-term outlook

The outlook for older breast cancer survivors is generally positive. Many people live for years or decades after treatment and enjoy a good quality of life. With regular checkups, healthy habits, and support for any late effects, you can live fully and independently. Your age is not a barrier to feeling well — you deserve caring, considered follow-up.
