Admit it. At some point in your life you have thought about what you would do if a doctor said the three life-altering words, “you have cancer”. Not too long ago, people would start checking off things listed on their bucket list, saying goodbye to friends and family, and determine how they want to spend their final days. Thankfully now, we can thank scientists for creating multiple treatments for this this potentially deathly disease.
Instead of writing a blog about how cancerous treatments work, I wanted to go a step before that. Why do some people get diagnosed with cancer and others don’t? Being that almost 50% of my family has been diagnosed while I have some friends who can only think of distant relatives that have been, this has always been a question pondering in the back of my mind. Is it the luck of the draw (paradoxically)? Or are cancerous cells in peoples genes?
Alternative Hypothesis: Cancerous cells are in peoples genes making it hereditary, meaning if someone in their family had or has cancer, the chances of them getting cancer increase.
Null Hypothesis: Cancerous cells are not in peoples genetic. One is simply un-lucky if they get diagnosed with it.
What is Cancer?
How normal cells work: Every day, each cell in our body has a different job to complete. The cells could either get damaged or die while completing this special job. If they get damaged, they can repair themselves, which is also known as DNA repair. During DNA repair, the cells use a series of enzymes to restore the DNA the cell was originally holding. If this fails, the cell will self-destruct and grow into a new, healthy cell so our bodies can operate properly.
How cancer cells work: Unlike normal cells, cancer cells do not die. They make an abundance amount of cells until they start to crowd out the normal cells. The part of the body that is overpopulated with the cancerous cells begins to work inefficiently. The cells are usually found in lumps, also known as tumors. And the worst part of it all is when metastasis occurs. Metastasis is when these cells could potentially spread to other parts of the body.
With having to consider multiple variables, scientists are still unsure if and how cancerous cells are created or if the normal cell is “triggered” into a cancerous one. So what increases our chances to get cancer more? Anything that falls under genetics such as family genes and age or our environments impacts such as smoking and being overweight.
Typically, if a family member has been diagnosed with cancer, the risk of that person
getting cancer is higher. Cancer is a genetic disease, meaning our genes control the way our cells function. But have no worry! Genetic changes develop throughout our lifetime
from the cells dividing wrong. This could be a disadvantage if a person smokes, or
develops an unhealthy lifestyle. This is an advantage if a person does just the opposite of that. Only about 5% of cancer diagnoses are hereditary, the most common being breast cancer. BRCA is a test to see if breast
cancer runs in your genes. Even if tested positive, there is a slim chance that person may not develop cancer. Not considering breast cancer, 95% of cancer diagnosis are by chance.
Ways to Reduce your Risk
- A Healthy Immune system
- This is a persons’ #1 defense mechanism against diseases. Chronic diseases can hurt the cells, making them more vulnerable.
- A Healthy Lifestyle!
I’m going to leave you with one question: Why do only some people get sunburnt?
Think of the sun as the cancer. It surrounds us, just like the cells make up our being. Some people get burnt, just like some cells overpopulate. While others don’t get burnt, just like some cells don’t overpopulate. Our genetics are all different, everything happens by chance. In the end, the Null Hypothesis was correct.
