Answers
Cancer - ANSWER abnormal uncontrollable multiplication of cells that can lead to death
Tumor - ANSWER mass of tissues with no purpose
Benign tumor - ANSWER a mass of cells enclosed in a membrane, does not penetrate
other tissues
Malignant tumor - ANSWER can invade surrounding structures including blood vessels,
lymphatic system, and nerves
Biopsy - ANSWER procedure done to confirm if a person has cancer
Metastasis - ANSWER the spread of the cancer cells, moving away from primary tumor
Metastasizing - ANSWER traveling and seeding process of cancerous cells
Metastases - ANSWER new tumors/secondary tumors
Remission - ANSWER signs and symptoms of cancer disappearing
Stages : description - ANSWER o : early cancer, present only where originated
1 : more extensive cancer w/ higher numbers
2 : indicating greater tumor size and/or degree
3 : the cancer has spread to nearby lymph nodes/organs
4 : advanced cancer that has spread to another organ
Causes of cancer - ANSWER role of DNA, tobacco and alcohol use, dietary factors,

Macrophages - ANSWER eat dead tissue after pathogen dies (innate)
Adaptive immune system - ANSWER immunity that is built up over time from exposure
to pathogens
Lymphocytes - ANSWER T cell ands B cells, they recognize one specific antigen and
when present attack, hold memory
Antigens/antibodies - ANSWER pathogen triggered immune response = antigen
Specialized proteins that recognize/neutralize = antibodies
