Cancer Research: Lung cancer survival rates improve with CT scan follow-up ♦ COPD heightens deadly lung cancer risk in smokers ♦ Genetic screening of brain metastases reveals new treatment

Differences between tumors of younger and older colorectal cancer patients  Tumors in younger colorectal cancer patients may be molecularly distinct from those of older patients, and that these differences are related to the way genes are switched on and off (epigenetics) in the tumors of the younger patients and may lead to better treatment options.
Genetic screening of brain metastases could reveal new targets for treatment Unravelling the genetic sequences of cancer that has spread to the brain could offer unexpected targets for effective treatment
Lung cancer survival rates improve with CT scan follow-up Patients with recurrent lung cancer have better post-surgery survival rates if their management includes a follow-up program based on computer tomography of the chest.
Differences found between smokers and nonsmokers who develop lung cancer Tobacco smoke is known to be the main risk factor for non-small cell lung cancer (NSCLC), although non-smokers can get it too. The incidence among non-smokers is increasing in many countries. Now a group of researchers has found significant differences in clinical particularities and survival between smokers and nonsmokers who develop NSCLC.
COPD heightens deadly lung cancer risk in smokers Smokers who have chronic obstructive pulmonary disorder may face nearly twice the risk of getting small cell lung cancer -- the deadliest form of lung cancer -- than smokers who don't have COPD.
