Can a person have stage 4 lung cancer and not know it?

How long can you have lung cancer without knowing?

Early lung cancer does not alert obvious physical changes. Moreover, patients can live with lung cancer for many years before they show any signs or symptoms. For example, it takes around eight years for a type of lung cancer known as squamous cell carcinoma to reach a size of 30 mm when it is most commonly diagnosed.

Can you live with lung cancer and not know?

Patients can (and usually do) live with lung cancer for many years before it becomes apparent. Early lung cancer is largely asymptomatic and internalisation of tumours means patients are not alerted by obvious physical changes.

Can you have metastatic lung cancer with no symptoms?

Note: Sometimes, there are no symptoms. In most cases, metastatic cancer to the lung is a sign that the cancer has spread into the bloodstream. Usually cancer will be present even in places not seen by CT scans.

What is the life expectancy of someone with metastatic lung cancer?

The 5-year survival rate for metastatic NSCLC is about 7%. If the cancer only spreads to nearby tissue, the rate improves to 35%. People with localized lung cancer, which has not spread at all, have a 63% survival rate.

Which is the most common site for metastasis in lung cancer?

Results: The most frequent metastatic sites were the nervous system, bone, liver, respiratory system, and adrenal gland. Liver (35%) and nervous system (47%) metastases were common in patients with metastases from small cell lung cancer, and bone (39%) and respiratory system (22%) metastases in adenocarcinoma.

What is a lung cancer cough like?

A lung cancer cough can either be wet or dry cough and it can occur at any time of day. Many individuals note that the cough interferes with their sleep and feels similar to symptoms of allergies or a respiratory infection.
