For the year 2009, around 159,390 people are projected to have died in the United States alone due to the cancer of the lungs, which is more than the number of deaths from colon, breast or prostate cancer combined. For those whose cancer tumor in the lungs has already spread towards the other parts of the body, only 2% are alive after a five – year diagnosis. Lung cancer survival rates for the initial stage are higher with a 49% chance of survival for a five – year period.
When human cells divide and multiply without constrain, they become cancer cells. The malignant cells then from a mass or tumor that are different from the tissues from where it came from, reduces the ability of the normal cells or tissues to function. This tumor not only seeks to invade and infect other healthy tissues near them but could infect other tissues in the different systems of the body as well. At the initial stage when the cancer tumor in lung is still small (not reaching 2 centimetres) the lung cancer survival rates goes as high as 50% chance of survival in a 5 year period. When the tumor reaches 2 centimetres but does not exceed 5 centimetres, the cancer has advanced to its next phase or stage 2.
When the malignant tumor infect the lymph nodes or other organs through the use of the blood vessels this process is called metastasis. The cancer tumor is then called a primary tumor, while the other systems of the body that are infected with the cancer cells, are called secondary or metastatic tumor. When this process happens, the lung cancer stage has reached its final phase. Lung cancer survival rates during this period drop down to below 10% chance of survival in a 5 year period.
There are a variety of factors that affect one’s lung cancer survival rates. The grade of the cancer tumor makes a huge impact to one’s cure. A tumor at the worst case has an exponential growth that could spread to the other systems of the body in a matter of months. One must go to a specialist if they see any signs of this malignant disease.
