Hereditary  Cancer   Testing   checks  for    inherited gene mutations that  increase  cancer  risk.  It  helps identify individuals at higher  risk  before  symptoms appear. Common genes tested  include  BRCA1  and BRCA2  for   breast    and    ovarian    cancer.   Early detection enables preventive measures and tailored screening   plans.   Results     guide      personalized treatment and lifestyle decisions. Testing   supports families in    understanding   inherited  cancer  risks.
