Cancer refers to a group of over 100 diseases characterized by uncontrolled cell growth and the ability to invade other tissues. It originates from damaged DNA that is not repaired in cancer cells, leading to the formation of tumors, which can metastasize to other body parts. The document identifies various types of cancer, explains the differences between benign and malignant tumors, and highlights that cancer behavior can vary significantly between types.

Introduction

2. › general name for a group of more than 100 diseases
› abnormal cells grow out of control
› Untreated cancers can cause serious illness and death.
What Is Cancer?

3. › trillions of living cells
› Normal body cells grow, divide to make new cells, and die
in an orderly way
› During the early years of a person’s life, normal cells divide
faster to allow the person to grow.
› After the person becomes an adult, most cells divide only
to replace worn-out or dying cells or to repair injuries.
How normal cells act

4. › start to grow out of control
› Cancer cell growth is different from normal cell growth
› Instead of dying, cancer cells continue to grow and form
new, abnormal cells.
› Cancer cells can also invade (grow into) other tissues,
something that normal cells can’t do.
› Growing out of control and invading other tissue
How cancer starts

5. › changes to their DNA (deoxyribonucleic acid)
› DNA is in every cell and it directs all its actions
› In a normal cell, when DNA is damaged the cell either
repairs the damage or dies.
› In cancer cells, the damaged DNA is not repaired, but the
cell doesn’t die like it should.
› Instead, the cell goes on making new cells that the body
doesn’t need. These new cells all have the same damaged
DNA as the first cell does.

6. › People can inherit abnormal or faulty DNA
› This happen while a normal cell is reproducing or by something in
the environment.
› DNA damage may caused by smthng obvious like cigarette smoking
or sun exposure.
› But it’s rare to know exactly what cause any one person’s cancer.
› Most cases, the cancer cells form a tumour, over time, the tumours
can invade nearby n.tissue, crowd it out or push it aside.
› Like leukemia  rarely form tumours.
› Instead these c.cells involve the blood and blood-forming organs and
circulate through other tissues where they grow.

7. › C.cells often travel to other parts of the body where they
can grow and form new tumours that crowd out normal
tissue.
› It happens when c.cells get into the body’s b.stream or
lymph vessels .
› The process of cancer spreading is called metastasis.
› No matter where a cancer may spread, always named
based on the place where it started. For instance, colon
cancer that spread to the liver  metastatic colon cancer
 not liver cancer
How cancer spreads

8. › Different types of cancer can behave very differently
› For instance, lung cancer and skin cancer are very
different diseases.
› They grow at different rates and respond to different
treatments.
How cancers differ

9. › A tumour is an abnormal lump or collection of cells
› but not all tumours are cancer
› tumours that aren’t cancer are called benign.
› Benign tumors can cause problems -grow very large and
press on healthy organs and tissues
› can’t grow into (invade) other tissues.
› can’t spread to other parts of the body (metastasize).
› These tumors are seldom life threatening
Tumours that are not cancer

30. Kaposi Sarcoma
cancer that causes
lesions (abnormal
tissue) to grow in
the skin; the
mucous
membranes lining
the mouth, nose,
and throat; lymph
nodes; or other
organs.

31. › is a group of conditions in which tumors grow inside a
woman's uterus (womb).
Gestational Trophoblastic Disease

32. Hodgkin Disease

Lymphoma is a cancer of
a part of the immune
system called the lymph
system.

33. Kidney Cancer

34. Laryngeal and Hypopharyngeal Cancer

cancers. They are made up of
special kinds of cells called
neuroendocrine cells.
