Abstract: The present invention relates to a method of identifying whether or not an individual has a cancer, a pre-invasive lesion that will progress to a cancer, or a pre-cancerous cell population that will progress to a cancer based on a methylation heterogeneity index (MHI). The present invention also relates to a method of treating and/or preventing a cancer and/or treating a pre-invasive lesion that will progress to a cancer or a pre-cancerous cell population that will progress to a cancer in an individual, the method comprising: identifying a cancer, a pre-invasive lesion that will progress to a cancer, or a pre-cancerous cell population that will progress to a cancer based on an MHI. The present invention also relates to an MHI and uses thereof, for identifying in an individual a cancer, a pre-invasive lesion that will progress to a cancer, or a pre-cancerous cell population that will progress to a cancer.

Abstract: The present invention relates to a method of identifying a pre-invasive lung lesion in an individual that will progress to an invasive lung cancer involving determining the presence or absence of a molecular signature. The present invention also relates to a method of treating a pre-invasive lung lesion and/or treating and/or preventing an invasive lung cancer in an individual comprising involving determining the presence or absence of a molecular signature. The present invention further relates to a molecular signature, and uses thereof, for identifying whether or not an individual has a pre-invasive lung lesion that will progress to an invasive lung cancer.
