The meaning of inheriting an increased probability of acquiring a certain form of cancer. Introduction: Cancer is defined as the condition in which the cells start showing abnormal and uncontrolled growth. The main causes of this condition are mutations which affect the property of contact inhibition among different types of cells. The substances causing the mutation are called carcinogens. Genomic sequencing is the latest technique focused on studying different aspects of genes that contribute to cancer development and also different genetic mutations that can cause cancer.

Question

Neurofibromatosis type 1 (NF1) is an inherited is an inheritent dominant disorder. The phenotype usually involves the production of many skin neurofibromas. Answer the following question about the disorder: The rarer form of neurofibromatosis is called segmental neurofibromatosis. In this form of the disease, neither parent of the patient has any clinical sign of the disease, and the tumors in the patient are restricted to one part of the body. Suggest an explanation for the genesis of segmental neurofibromatosis that clarifies why it is restricted to one part of the body.

Summary Introduction

To determine: The subsequent event(s) that must occur after acquiring a certain form of cancer.

Introduction: Cancer genes are mostly present in the autosomes and are not inherited by a person. This type of cancer is called sporadic cancer and if the mutation occurs in the germ cells it can be inherited by the offspring and this type of cell is called familial cancer.
