Cancer And Asbestos
Overview
Asbestos is a natural mineral that was once used in building materials. When asbestos fibres are breathed in, they can get stuck in the lungs and cause damage over many years. This damage can lead to several types of cancer, most commonly mesothelioma (a cancer of the lining of the lungs) and lung cancer. Asbestos-related cancer usually appears decades after the exposure.
Key facts
- Asbestos-related cancers take many years to develop — often 20 to 50 years after exposure.
- The most common types are mesothelioma and lung cancer.
- If you have been exposed to asbestos in the past, tell your doctor, even if you feel well.
Asbestos-related cancer is relatively uncommon compared to other cancers, but it is still a serious health concern for people who worked with asbestos or lived with someone who did.
It mainly affects people who worked with asbestos in jobs like construction, shipbuilding, plumbing, or insulation. People who lived with these workers or handled their clothing can also be affected. Men are affected more often than women because of the jobs they held in the past.
Symptoms
- Severe trouble breathing at rest
- Coughing up a large amount of blood
- Sudden sharp chest pain that does not go away
- ⚠A cough that is new or getting much worse
- ⚠Fever with a chest cough
- ⚠Unexplained weight loss
- ⚠Pain in the chest that is constant or getting worse
Common symptoms
- Persistent cough that doesn't go away
- Shortness of breath
- Chest or rib pain
- Unexplained weight loss
- Tiredness or fatigue
- Lumps or swelling in the belly area (in some types)
Symptoms in children
- Children are rarely diagnosed with asbestos-related cancer because it usually takes decades to appear. However, children can be exposed at home (for example, from a parent's work clothes) and may develop the disease later in life.
Symptoms in older adults
- Older adults are most commonly affected because of the long delay between exposure and diagnosis. Symptoms may be mistaken for normal aging or other chest conditions, so it's important to mention past asbestos exposure to your doctor.
Causes
Main causes
- Breathing in asbestos fibres over a long period, usually in a workplace
- Exposure to asbestos dust from old buildings or materials during home renovation
- Living with an asbestos worker who brought fibres home on their clothes
Risk factors
- Working in construction, shipyards, or insulation for many years
- Working in asbestos mining or manufacturing
- Family member who worked with asbestos
- Smoking combined with asbestos exposure (greatly increases the risk)
When to see a doctor
See a doctor urgently if:
- If you have new or worsening cough, chest pain, or breathlessness, see your doctor within a day or two.
Book a routine appointment if:
- If you were exposed to asbestos in the past, mention this at your next check-up, even if you have no symptoms.
Diagnosis
Your doctor will start by asking about your symptoms, your medical history, and your history of asbestos exposure. They will listen to your chest and may order tests to look at your lungs.
Tests that may be done
- Chest X-ray
- CT scan (a detailed scan of the body)
- Breathing tests
- Blood tests, which may include biomarkers (substances in the blood linked to cancer)
- Biopsy (taking a small sample of tissue to check for cancer cells)
What to expect at your appointment
Diagnosis can take a little time. If you have symptoms, your doctor will usually refer you to a specialist (often a lung specialist or cancer doctor). Not all tests mean you have cancer — they help your doctor find out what is causing your symptoms.
Treatment
Treatment for asbestos-related cancer depends on the type, stage, and your general health. The goals are to remove or control the cancer and help you feel as well as possible. Your cancer team will discuss the options with you in detail.
Self-care at home
- Follow the treatment plan and attend all appointments
- Talk to your doctor before using any complementary or over-the-counter therapies
- Keep a note of symptoms and side effects to discuss with your team
Medical treatments
Treatment approaches may include surgery to remove the cancer, chemotherapy (medicines that kill cancer cells), radiation therapy (high-energy rays), and newer treatments that help your immune system fight the cancer. A specialist team will tailor the plan to your situation. Medicines may be used to control pain and other symptoms, but the choice of any medicine must be made by your doctor.
When is surgery considered?
Surgery may be an option when the cancer is detected early and is only in one area. For some people, surgery can remove the cancer; for others, it helps control symptoms.
Living with this condition
Living with asbestos-related cancer can be challenging. Take things at your own pace, rest when you need to, and ask for help with daily tasks if you need it. Your healthcare team can guide you on managing breathlessness and other symptoms.
Lifestyle tips
- If you smoke, ask your doctor for help with quitting. Quitting can improve your health and how well your treatment works.
- Stay as active as you feel able to – gentle activity can help your energy and mood.
- Talk to your family about what you are going through. You don't have to protect them on your own.
Diet and exercise
Eating a healthy diet with enough protein can help you stay strong during treatment. It is also fine to eat smaller meals more often if you feel full quickly. Aim to stay gently active, such as short walks, but check with your doctor about what is safe for you.
Mental health and emotional wellbeing
A cancer diagnosis can bring anxiety, sadness, and fear. These feelings are normal. It is important to talk about them with your cancer team, who can link you to counselling or supportive care. If you are in crisis, please reach out to emergency services or a crisis helpline in your country.
Prevention
Asbestos-related cancer can be prevented by avoiding exposure to asbestos. If you live or work in an older building, check the condition of materials. Never disturb asbestos yourself — hire a licensed professional for removal.
Complications
If left untreated
- The cancer may spread to nearby tissues and organs
- Breathing can become much more difficult
- Severe pain that is harder to control
- Fluid build-up around the lungs that requires drainage
Long-term outlook
An asbestos-related cancer diagnosis is serious, but there is always reason for hope. Treatments have improved, and some people live many years with good quality of life. Your healthcare team will work with you to control the cancer and manage symptoms, and you are not alone on this journey.
