An Overview Of Cancer



An Overview of​ Cancer
Cancer is​ a​ disease that affects cells of​ the​ body. ​
Cells are extremely small units that build together and​ ​ form all living things, which include human beings. ​
In any given person’s body, you will find billions of​ cells.
Cancer occurs when unusual and​ ​ abnormal cells grow and​ ​ spread very quickly. ​
Normal cells in the​ body divide, grow to a​ certain size and​ ​ then stop. ​
Over the​ course of​ time, cells will even die. ​
Cancer cells do not follow this normal pattern of​ division and​ ​ growth, however. ​
They divide very quickly and​ ​ just continue to grow. ​
Normally, cancer cells do not die and​ ​ they clump together in groups to form what are called tumors.
The cancer cells in a​ tumor can damage and​ ​ destroy surrounding healthy body tissues. ​
When these healthy tissues are damaged and​ ​ destroyed, the​ person with the​ tumor can become very sick.
Cancer is​ capable to spreading to other parts of​ the​ body, as​ well. ​
it​ is​ not unusual for​ part of​ a​ tumor to break off and​ ​ travel to a​ distant area. ​
Once that piece of​ the​ tumor comes to a​ stop in another area of​ the​ body, it​ will continue to grow and​ ​ can create a​ new tumor. ​
When cancer spreads like this, it​ is​ called metastasis.
When in the​ body, cancer can cause a​ person to feel very sick. ​
Since early detection is​ a​ big factor in treatment, it​ is​ good to be aware of​ the​ signs of​ this disease. ​
Some signs of​ cancer include
· a​ lump in the​ breast or​ testicles
· a​ change in the​ skin, a​ wart or​ a​ mole
· Persistent sore throat that doesn’t heal
· a​ significant change in bladder and​ ​ bowel movements
· Coughing blood or​ a​ persistent cough that won’t stop
· Indigestion and​ ​ trouble swallowing
· Unusual bleeding or​ vaginal discharge
· Chronic fatigue
Many of​ these symptoms can be from other illnesses which are not as​ serious as​ cancer. ​
However, if​ ​ you are ever faced with any of​ the​ symptoms above, it​ might be a​ good idea to see your family physician right away. ​
Although the​ exact cause of​ cancer is​ still somewhat of​ a​ mystery, it​ is​ known that cancer is​ not contagious. ​
You cannot catch cancer like you can the​ common cold. ​
Unhealthy habits like smoking and​ ​ excess drinking can increase your chances of​ getting cancer, but doctors aren’t sure why some people get this serious disease and​ ​ others do not.
