Cancer

Five things I learned about cancer:
     1.) Cancer cells form from regular cells.
     2.) Cancer isn't confined to one area of the body at a time; it can travel. (metastasis)
     3.) Not all tumors are cancerous. The the difference is whether they are benign or malignant.
     4.) Cancer usually comes from a persons choice to live an unhealthy life. (junk food, lazy, smoking, etc.)
     5.) The immune system can't help fight cancer.

Two questions that I still have about cancer are:
     1.) Can cancer occur in every organ in the human body? (i.e. the eye)
     2.) Can injuries/stress cause cancer?

One thing I liked about the cancer unit is I learned a lot about how cancer forms and progresses.

One thing I disliked about the cancer unit is we had to work in teams that we weren't able to choose.
