Does lung cancer progress quickly?

Can lung cancer develop in 6 months?

Small cell lung cancer is notorious for growing extremely fast with death often occurring within 6 months when no treatment is received. This rapid growth, however, makes this type of cancer susceptible to chemotherapy agents. Lung cancers sometimes grow extremely slowly.

How fast does lung cancer go from Stage 1 to Stage 4?

It takes about three to six months for most lung cancers to double their size. Therefore, it could take several years for a typical lung cancer to reach a size at which it could be diagnosed on a chest X-ray.

Do you feel ill with lung cancer?

Cancer anywhere in the body can cause a person to feel unwell in a general way. Loss of appetite can cause weight loss and muscle loss. Fatigue and weakness can further worsen a person’s ability to breathe. Muscle loss also contributes to weakness and loss of mobility.

What are the odds of beating lung cancer?

The five-year survival rate for lung cancer is 56 percent for cases detected when the disease is still localized (within the lungs). However, only 16 percent of lung cancer cases are diagnosed at an early stage. For distant tumors (spread to other organs) the five-year survival rate is only 5 percent.

How long do people live with Stage 4 lung cancer?

Stage 4 lung cancer usually has a poor prognosis. One study found that depending on the stage of the metastases (spread) the average survival time following diagnosis of stage 4 lung cancer ranged from 6.3 months to 11.4 months.

How successful is chemotherapy for lung cancer?

More important to patients, however, may be the comparison of 1 and 2 year survival; 29% of those treated with chemotherapy were alive at 1 year compared with 20% in the supportive care arm, and 2 year survival was doubled in the chemotherapy arm from 5% to 10%.

What is the most aggressive form of lung cancer?

SCLC is very rare in people who have never smoked. SCLC is the most aggressive form of lung cancer. It usually starts in the breathing tubes (bronchi) in the center of the chest. Although the cancer cells are small, they grow very quickly and create large tumors.
