Oncogenomics is a sub-field of genomics that characterizes cancer-associated genes.It focuses on genomic, epigenomic and transcript alterations in cancer. Cancer is a genetic disease caused by accumulation of DNA mutations and epigenetic alterations leading to unrestrained cell proliferation and neoplasm formation.

The central role of DNA damage and epigenetic defects in DNA repair genes in carcinogenesis. DNA damage is considered to be the primary cause of cancer. [17] More than 60,000 new naturally-occurring instances of DNA damage arise, on average, per human cell, per day, due to endogenous cellular processes (see article DNA damage (naturally occurring)).
Don't skip the genetic counseling, said the task force's Mangione. BRCA testing can cause anxiety and sometimes gives confusing results, finding mutations that might not be dangerous — things ...
The unique mutations for each cancer allowed for the 21 samples to be categorized based on type and subtype of cancer, showing a relationship between mutations and the type of resulting cancer. While the group was able to identify these mutations they were unable to determine the underlying mechanisms resulting in them. [10]
The Cancer Genome Atlas (TCGA) is a project to catalogue the genomic alterations responsible for cancer using genome sequencing and bioinformatics. [1] [2] The overarching goal was to apply high-throughput genome analysis techniques to improve the ability to diagnose, treat, and prevent cancer through a better understanding of the genetic basis of the disease.
BRCA gene mutations: The tumor suppressing BRCA genes frequently help in cancer prevention. They control how cells divide and develop and help repair DNA damage BRCA gene abnormalities, however, can the likelihood of having specific cancers is raised. Cancers BRCA1 and BRCA2 are the two BRCA recognized cancer-causing gene alterations.
A genetic counsellor discussing a pedigree with a client. Genetic counseling is the process of investigating individuals and families affected by or at risk of genetic disorders to help them understand and adapt to the medical, psychological and familial implications of genetic contributions to disease.
