cancer test review Flashcards
HPV is responsible for
cervical cancer
What is Cancer?
-is a disease characterized by cells that grow and divide without respect to normal limits
-Invade and destroy adjacent tissues
-May spread to distant site by metastasis
-Aggressive growth of cells that doesn’t stop
oncologist
studies cancer
which vaccine helps protect against cervical cancer
HPV
biopsy
a procedure in which the doctor removes a sample of tissue for examination to rule out cancer
incisional vs excisional biopsy
incisional: removal of part of a tumor
excisional: removal of entire tumor
anaplastic
well differentiated cells
carcinogens
Agents that cause cancer (chemicals, drugs, radiation, viruses)
Local symptoms (more common but specific to an area)
-Unusual lumps or swelling (tumor)
-Hemorrhage (bleeding)
-Pain and/or ulceration
-Compression of surrounding tissues may causes symptoms such as jaundice
anaplasia
loss of differentiation of cell
henrietta lacks suffered from what cancer

type of cancer that affects children and young adults
melanoma
surgical oncology
uses surgery to treat cancer
bening tumour
does not kill the host
the study of cancer
oncology
malignant tumor
can kill the host
the extent or severity of a person’s cancer is known as
staging
prognosis
-whether the cancer has spread
If caught early, some can be cured
-the predicted outcome is based on pathological staging
most common type of skin cancer
basal cell carcinoma
most severe form of skin cancer
melanoma
what does the ABCDE method of mole assessments mean
it assesses moles that could be cancerous using these prompts. A stands for asymmetry. Symmetrical is healthy and asymmetrical is unhealthy. B stands for border. even edges is healthy and rough edges is unhealthy. C stands for color, 1 color means healthy, uneven colors mean unhealthy. D stands for diameter, 6mm or less is healthy and more is unhealthy. E stands for evolving. It is unhealthy if it is growing, changing color, becoming uneven, etc.
where was HeLa Cells harvested and what is so special about HeLa cells
HeLa cells have been harvested when a doctor at John Hopkins hospital preformed a biopsy and took pieces of her tumor. What’s so special about her cells is that they are immortal, so they never die off and they always continue dividing
list 6 contributions to healthcare that HeLa cells helped with
-polio vaccine
-human papilloma vaccine
-IVF vaccine
-covid 19 vaccine
-genetics and gene mapping
-cervical cancer research
false positive and false negative
during his cancer screening there might be a false negative result, resulting in him actually having cancer, or a false positive result, meaning he does not actually have cancer. these are risks linked to cancer screening.
