What are the main causes of lung cancer?
The
main risk factor for lung cancer is smoking, as well as passive
second-hand smoking. Around 80% of lung cancer related deaths are
attributed to smoking. The more a person smokes, and for a longer period
of time, the higher the risk. Fortunately, smokers can still lower the
risk by quitting, since the damaged lung tissue gradually repairs
itself. Other causes of lung cancer include exposure to radon gas and
asbestos. It is also known that people who have a family history of lung
cancer are at a higher risk as well.
Can lung cancer be detected early?
Lung
cancer symptoms do not often appear at an early stage of the disease.
Being aware and alert to the symptoms is important, but we also
recommended that people who are at high risk of getting lung cancer to
go through a series of diagnostic procedures regularly. Early detection
of lung cancer enables us to start treatment at an early stage and,
before the cancer starts spreading to other organs. The recommended
diagnostic procedures should include a spirometry test, ergometer test,
CT scan and a specialist consultation.
What are the symptoms and signs for lung cancer?
As
mentioned, the signs of lung cancer are not usually noticeable at an
early stage. If you are noticing the following signs, it is important
not to ignore them, and go get testes:
- Constant chest pain that worsen when breathing
- A cough that goes on for a long time without getting better, or getting worse, coughing blood
- Repeated cases of pneumonia or bronchitis
- Swelling of the neck and face
- Shortness of breath, wheezing sound when breathing
- Significant weight loss or lack of appetite
- Weakness and fatigue
How is lung cancer treated?
The
treatment method depends on the type of lung cancer and condition of
the patient, as well as how far the cancer has spread. Surgery,
radiotherapy, chemotherapy and targeted therapy are all used to treat
lung cancer. Surgery is used to remove tumours when it is possible to
remove all tumours, while the other methods are used to kill the
cancerous cells or stop them from growing.
