Inside almost every single cell in your body is a structure called the nucleus. The nucleus is the control centre of the cell. Inside the nucleus are 23 pairs of chromosomes made up of genes. Genes are coded messages that tell cells how to behave. They control how our bodies grow and develop. We each have about 25,000 genes. All cancers develop bec...
Some faulty genes that increase the risk of cancer can be passed on from parent to child. These are inherited cancer gene faults. They occur when there is a fault in the genes in an egg or sperm cell at the time of conception. These faults in the initial sperm or egg cell are copied into every single cell in the body. The faulty genes can then pass...
Cancers due to inherited faulty genes are much less common than cancers due to gene changes caused by ageing or other factors. Most cancers develop because of a combination of chance and our environment, not because we have inherited a specific cancer gene fault. Genetic specialists estimate that between 5 and 10 in every 100 cancers (5 to 10%) dia...
Most people who have relatives with cancer will not have inherited a faulty gene. Cancer mostly occurs in older people. It is a common disease. 1 in 2 people in the UK (50%) born after 1960 will be diagnosed with some form of cancer during their lifetime. So, most families will have at least one person who has or has had cancer. Having a couple of ...
Talk to your GP if you think that you may have a strong family history of cancer. Your GP will ask you about your family and how many members have had cancer, so it is important to have as much information about your relatives’ cancer diagnoses as possible. If they think that you might be at increased risk, they can refer you to a genetics clinic. ...
Your doctor or a genetic counsellor will be able to give you an idea of how much your cancer risk is increased compared to the general population. They might suggest that you have regular monitoring for particular cancers. Or treatment such as surgery to try to reduce the risk of developing cancer. You can find out more about the options if you hav...
Some inherited cancer genes are more likely to cause cancer than others. As well as a gene fault, many other factors need to be in place for a cancer to develop. Because of this, the effect of the cancer gene may appear to skip a generation. For example, a parent may have the gene fault and not develop cancer but their child who inherits the same g...
Aug 25, 2023 · Inherited risk and family history aren’t the same thing, even though some people may use them interchangeably. Inherited risks for cancer due to hereditary cancer syndromes are characterized by a known genetic link. Having a family history of cancer may increase the risk for developing cancer even in patients who don’t have hereditary ...

Understanding Cancer. In simple terms, cancer is a group of more than 100 diseases that develop across time and involve the uncontrolled division of the body's cells. Although cancer can develop in virtually any of the body's tissues, and each type of cancer has its unique features, the basic processes that produce cancer are quite similar in ...
