Verified step by step guidance1
Understand the basic characteristics of normal cell growth and division: Normal cells follow a regulated cycle of growth, division, and death (apoptosis). They respond to signals that control their proliferation and stop dividing when necessary.
Learn about the concept of apoptosis: Apoptosis is a programmed cell death mechanism that helps maintain healthy tissue by eliminating damaged or unnecessary cells. Normal cells undergo apoptosis when they are damaged or no longer needed.
Explore how cancer cells evade apoptosis: Cancer cells often develop mutations that allow them to bypass apoptosis, leading to uncontrolled growth and accumulation of cells that should have died.
Examine the uncontrolled division of cancer cells: Unlike normal cells, cancer cells divide uncontrollably due to mutations in genes that regulate the cell cycle. This results in the formation of tumors and potential spread to other parts of the body.
Consider the implications of uncontrolled growth: The ability of cancer cells to evade apoptosis and divide uncontrollably is a key factor in the progression of cancer, making it difficult to treat and manage.
