Answers (100% Correct Answers)
Identify the most prevalent cancer found in men, women, and children.—
Answer: • Men: Prostate, lung, Colorectal
• Women: Breast, Lung, Colorectal
• Children: Leukemia, Brain/ONS, soft tissue (like heart)
Normal Cells—
Answer: • Mortal (die after ~50 divisions)
• Contact inhibition
- cell growth stops when cells come into contact with each other
• Stay bound together
• Controlled cell death (apoptosis)
• Controlled cell division
• Control of angiogenesis
- Angiogenesis: the continuation of forming blood vessels to get nutrients
• Mature into functional cells
Cancer Cells—
Answer: • Immortal (divide indefinitely) if have enough access to nutrients
• Loss of contact inhibition
- Leads to solid tumors
• Can easily detach from each other
,Inquire through: | Professional | Confidential Support
• Unresponsive to apoptosis
• Increased rate of cell division
• Unregulated angiogenesis
• Do not mature into functional cells
Classification and Nomenclature - Benign tumors—
Answer: • Named according to the tissues from which they arise, often include the
suffix "-oma"
• Lipoma (vs. liposarcoma)
• Leiomyoma (vs. leiomyosarcoma)
• Adenoma (vs. adenocarcinoma)
• Note: "-oma" can also be malignant
Carcinoma—
Answer: • Begins in the skin or in tissues that line or cover internal organs
(epithelial tumors)
• Adenocarcinoma
• Basal cell carcinoma
• Transitional cell carcinoma
Sarcoma—
Answer: • Begins in bone, cartilage, fat, muscle, blood vessels, or other connective
or supportive tissue
• Chondrosarcoma
• Osteosarcoma
Lymphoma—
Answer: Malignancy of lymphatic tissue
, Inquire through: | Professional | Confidential Support
Leukemia—
Answer: Malignancy of blood-forming cells
Myeloma—
Answer: Malignancy of plasma cells
Carcinoma in situ (CIS)—
Answer: • Pre-invasive epithelial malignant tumors of glandular or squamous cell
origin that have not broken through the basement membrane or invaded the
surrounding stroma
• Often seen in the cervical, skin, oral cavity, esophagus, bronchus, stomach, breast,
and endometrium
• Progression patterns
- Remain stable indefinitely.
- Progress to invasive and metastatic cancers.
- Regress and disappear.
