Treatment for lung cancer

Laser therapy for lung cancer

A laser is a very thin, focused beam of light that heats and destroys tissue. Lasers can focus very accurately on tiny areas.

You have the treatment in hospital in the endoscopy department or x-ray department. It takes about 30 minutes. 

You can have laser therapy along with other types of lung cancer treatment.

Why you might have laser therapy for lung cancer

You might have laser therapy if your cancer is blocking an airway and making you breathless. It can help you to breathe more easily again.

Side effects of laser therapy

Soreness and pain

You might have a sore throat. Taking painkillers for a few days helps.

Tell your nurse or doctor if you still have pain.

Bleeding

You might have some slight bleeding and have some blood in your sputum (phlegm). It might give you a metallic taste in your mouth. This usually gets better over a few days.

Tell your doctor if you cough up blood.

Possible risks of laser therapy

Laser therapy is a safe treatment. There are usually very few side effects and they tend to be mild. But all treatments have potential risks.

A collapsed lung (pneumothorax)

Air or gas can leak into the space around the lung and make it collapse. This makes you feel very breathless. It can get better on its own or your doctor can put in a small tube to expand the lung again.

Let your doctor know straight away if your breathing gets worse after your treatment.

Chest infection

Let your doctor know if you develop any signs of a chest infection. This includes having a high temperature and your phlegm (sputum) changing colour.

Changes to the airway tissue (wall)

The risk is small, but a hole can happen in the airway tissue (perforation) during laser therapy. Or changes may happen to the airway tissue, such as an ulcer forming.

Your doctor will take extra care to prevent this from happening.

If the cancer blocks the airway again

You can have the treatment again if the tumour starts to block the airway again. Or your doctor might suggest other treatment.

Living with lung cancer

There is support available during and after treatment to help you cope. This includes support from your clinical nurse specialist, cancer charities, community services, and family and friends.

Coping with breathlessness

Feeling short of breath can be hard to live with. It can make you feel tired and like everything is a struggle. But some things can help you to cope.
