Can you have two types of lung cancer at the same time?
Dual primary lung cancer refers to two or more primary cancers in different sites of one or both lungs, with either consistent or different histology but no association between two cancers. Based on the time when the tumors are identified, the disease can be classified as synchronous or metachronous .
Can you have several types of cancer at once?
Unfortunately a person can be diagnosed with two different types of primary cancer. This might be at different times in their life, or more unusually at the same time. I appreciate it can be hard to come to terms with one diagnosis, so having news about two different diagnoses must be quite overwhelming.
Which type of lung cancer is the most aggressive form?
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.
What are the chances of lung cancer coming back?
In general, the higher your stage, the more your cancer has spread, and the greater chance it’ll come back. For example, research shows that one in three people with stage I will have a recurrence. For those diagnosed with stage III, the lung cancer will return about 63% of the time.
What type of cancer is most likely to recur?
Some cancers are difficult to treat and have high rates of recurrence. Glioblastoma, for example, recurs in nearly all patients, despite treatment. The rate of recurrence among patients with ovarian cancer is also high at 85%.

Can you survive cancer 3 times?
Some cancers come back only once, while others reappear two or three times. But some recurrent cancers might never go away or be cured. This sounds scary, but many people can live months or years with the right treatment. For them, the cancer becomes more like a chronic illness, such as diabetes or heart disease.
Is second cancer curable?
In many cases, local and regional recurrences can be cured. Even when a cure isn’t possible, treatment may shrink your cancer to slow the cancer’s growth. This can relieve pain and other symptoms, and it may help you live longer.
Which type of lung cancer has worse prognosis?
SCLC has the most aggressive growth of all lung cancers, with a median survival time of only two to four months after diagnosis when untreated. (That is, by two to four months, half of all patients have died.) However, SCLC is also the type of lung cancer most responsive to radiation therapy and chemotherapy.
Which type of lung cancer has the best prognosis?
Adenocarcinoma is usually found in the outer parts of the lung and is more likely to be found before it has spread. People with a type of adenocarcinoma called adenocarcinoma in situ (previously called bronchioloalveolar carcinoma) tend to have a better outlook than those with other types of lung cancer.
Can you have lung cancer for years and not know it?
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.
How fast does lung cancer spread without treatment?
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.
