Final answer:
Understanding the gene expression pattern in a cancer cell can provide insight into the specific form of cancer. In the case of myc genes, overexpression can lead to the development of Burkitt's Lymphoma and the growth of tumors in the lymph system.
Step-by-step explanation:
Oncogenes are genes that can cause cancer when they are overexpressed or mutated. One example of an oncogene is the myc gene, which is involved in Burkitt's Lymphoma.
Overexpression of the myc gene transforms normal B cells into cancerous cells that continue to grow uncontrollably. This can lead to the development of tumors in the lymph system, including the jaw or mouth, which can interfere with eating.
