Is cancer curable? by Ergashova munisa an abstract

1. WHAT IS CANCER ITSELF?
Cancer is a genetic disease—that is, it is caused by changes to genes that control the way our cells function, especially how they grow and divide.Genetic changes that cause cancer can happen because:

• 
  of errors that occur as cells divide. 
  
• 
  of damage to DNA caused by harmful substances in the environment, such as the chemicals in tobacco smoke and ultraviolet rays from the sun. they were inherited from our parents. 
  

The body normally eliminates cells with damaged DNA before they turn cancerous. But the body’s ability to do so goes down as we age. This is part of the reason why there is a higher risk of cancer later in life.
Each person’s cancer has a unique combination of genetic changes. As the cancer continues to grow, additional changes will occur. Even within the same tumor, different cells may have different genetic changes.¹
A term for diseases in which abnormal cells divide without control and can invade nearby tissues. Cancer cells can also spread to other parts of the body through the blood and lymph systems.
As the name suggests, it is the disease and growing one. If one it starts to move, there can not be another way to escape or cure fully. In other words, one of the body's cells grow uncontrollably and spread to other parts of the body. The growing tumors can have bad effects to other parts of organs and organs may lose their own daily functions after welcoming the tumors.
For example, colon or colorectal cancer
Colon cancer symptoms are more noticeable in stages 3 and 4. In addition to the above symptoms, you might also experience:

• 
  excessive fatigue
  
• 
  unexplained weakness
  
• 
  unintentional weight loss
  
• 
  changes in your stool that last longer than a month
  
• 
  a feeling that your bowels won’t completely empty
  
• 
  vomiting
  

If colon cancer spreads to other parts of your body, you may also experience:

• 
  jaundice, or yellow eyes and skin
  
• 
  swelling in the hands or feet
  
• 
  breathing difficulties
  
• 
  chronic headaches
  
• 
  blurry vision
  
• 
  bone fractures²
  

All in all, Cancer is a type of disease that cannot be detected early, and it is a danger that spreads rapidly.
