Key points
- 1
Cancer is a broad term for a group of diseases in which abnormal cells grow and divide uncontrollably, potentially invading surrounding tissue and spreading to other parts of the body. There are over 200 different types of cancer, each with its own specific causes, symptoms, and treatment approaches, so experiences with cancer vary enormously between individuals.

What is Cancer?
Cancer is a broad term for a group of diseases in which abnormal cells grow and divide uncontrollably, potentially invading surrounding tissue and spreading to other parts of the body. There are over 200 different types of cancer, each with its own specific causes, symptoms, and treatment approaches, so experiences with cancer vary enormously between individuals.
Advances in early detection, screening, and treatment mean that survival rates for many cancers have improved significantly in recent decades. Treatment approaches, including surgery, chemotherapy, radiotherapy, and newer targeted or immune-based therapies, are tailored specifically to each individual's cancer type and stage.

Clinical context
Screening programmes catch several cancers before symptoms appear
National screening programmes — BowelScreen, BreastCheck, and CervicalCheck — are specifically designed to detect certain cancers, or the changes that can lead to them, before any symptoms develop, when treatment tends to be most effective.
03 · Act
When to See a Doctor
- 1You notice a new lump, unusual bleeding, or a persistent change in bowel or bladder habits
- 2You have unexplained weight loss, persistent fatigue, or unexplained pain
- 3A mole or skin lesion changes shape, colour, or size
- 4You have a family history of cancer and want to discuss your own risk or screening needs

Practical steps
Take Part in Screening Programmes When Invited
Attending BowelScreen, BreastCheck, or CervicalCheck when invited is one of the most effective things you can do to catch certain cancers early, often before symptoms even develop.
- 1Attend relevant national screening programmes.These catch several common cancers early, when treatment tends to be most effective.
- 2Get new or unusual symptoms checked promptly.Early investigation leads to earlier diagnosis and generally better outcomes if cancer is found.
- 3Maintain a healthy lifestyle.Not smoking, limiting alcohol, staying active, and maintaining a healthy weight all reduce risk for several cancer types.
- 4Know your family history.This can affect your personal risk and whether earlier or additional screening is recommended.
- 5Seek support if you or a loved one receive a diagnosis.Cancer support services offer practical and emotional support throughout diagnosis, treatment, and beyond.

BarnMD Bottom Line
Cancer outcomes have improved significantly with advances in screening, diagnosis, and treatment, though experiences vary greatly by cancer type.
National screening programmes catch several cancers early — attending when invited is one of the most valuable steps you can take.
