Lec 44 Flashcards
Healthy cell becomes a
before a cancer cell
benign cell
benign cell
increase reproduction and eventually becomes a malignant cancer cell/tumor which spreads
Cancer incidence
increases as age increases
Males mostly have
prostate cancer
Females mostly have
breast cancer
Cancer type that kills the most
lung cancer
what causes the change of a healthy cell to a benign cell and cancer cell
mutations
changes inDNA
Initiation
one mutation in one cell causes itself and its offspring to divide inappropriately
Progression
More and more random mutations
increase reproduction, survival, and spreading
Spread (metastasis)
Cell leave the primary tumor and establishes more tumors
Healthy cell to benign cell
Initiation
Benign cell to cancer cell
Progression
Cancer cell onward
Spreading/metastases
Misconceptions about cancer cells
cancer cells are not
trying to get worse
the mutations are random and are mostly bad but can also be bad for the cancer cell
Misconceptions about cancer cells
cancer cells do not reproduce
quickly
100 days per cell cycle
Healthy human cell reproduce every
24 hours
Misconceptions about cancer cells
cancer cells in a tumor are not
Identical
many different mutations from each cancer cell
Each cells have different destructive properties and vulnerabilities
Single cell DNA sequencing
would not notice all mutations in cancer cells because they are different
Misconceptions about cancer cells
most cells in a tumor are not
Cancer cells
Cancer cells recruit normal cells for support
