CANCER GENETIC CONSULTATION
CANCER GENETICS
Most cancers result from combination of genetic, environmental, and hormonal factors. About 5-10% of cancers are caused by a strong genetic predisposition or susceptibility to cancer due to a genetic variant in a high risk cancer gene. A cancer genetic consultation can help clarify your personal risks for cancer, genetic testing options available to you and/or your family members and further steps to either reduce or manage your risks of cancer. Dr Liani works closely with and supports genetic counsellors providing cancer genetic counselling services in South Africa.
Reasons for consultation:
-
Cancer in infants, children or adults which is or could be part of a broader cancer predisposition or genetic syndrome, e.g. neurofibromatosis type I or II, tuberous sclerosis, Von Hippel Lindau syndrome, MEN I/II syndrome, Fanconi anemia and other defects of DNA repair, Beckwith Wiedeman syndrome, Cowden syndrome (PTEN hamartoma tumour syndrome), hereditary nevoid basal cell carcinoma (Gorlin) syndrome etc.
-
Cancer genetic testing detecting a genetic cause of cancer which is unexpected, unusually complex or requiring correlation with clinical features to confirm the diagnosis and management plan.
What to expect:
Dr Liani will gather information from your family history and personal medical history. You will be examined for relevant clinical features (where indicated) before a discussion around the diagnosis or possible diagnosis, implications for yourself and other family members. Dr Liani may advise further genetic or other investigations and liaise with your referring doctor regarding a surveillance, management and follow up plan.
