Cancer Flashcards
1/3 of all cancer deaths are attributed to
Diet and physical activity habits
Proliferation
Cell division that replaces old cells and forms new cells
Differentiation
New cells develop the same structure and function as the cells they are replacing
Malignant neoplasm
Able to evade apoptosis. Ability to control differentiation and proliferation is impaired. Cells grow rapidly and evade other cells
Benign neoplasm
Same cell structure and function, but has lost its ability to control proliferation. Slower growth
Definition of cancer
Uncontrolled, unregulated cell growth and division, resultant tissue is termed a neoplasm
Breast cancer RFs
Genetics, age of menopause, age of menarche, age of first child, previous cancer and lifestyle
Breast cancer symptoms
Breast lumps, swelling, tenderness, skin irritation, thickening, nipple pain, scaliness
Colorectal cancer signs and symptoms
Rectal bleeding, blood in stool, change in bowel habits
Lung cancer signs and symptoms
Persistent cough, sputum (spit and phlegm) streaked with blood, chest pain and recurring pneumonia and chest pain
Prostrate cancer symptoms
Weak or interrupted urine flow, frequent urination, blood in urine, pain or burning in urine, pain in lower back, pelvis or upper thighs
Pulmonary limitation in cancer due to
Possible Surgical resection of lung tissue reducing maximal alveolar ventilation and diffusion area
Cardiovascular limitations
Chemo, radiation and hormone therapy can impact HE and systolic/diastolic function. Can cause impairments in LV function
Vascular limitations associated with cancer treatment
Can cause a decrease in RBCs and Hb conc through excessive blood loss, RBC destruction or deficient production
Skeletal muscle dysfunction due to cancer treatment
Muscle wasting and weakness due to treatment. Loss of lean mass can be caused by cache is, neuropathy, steroid treatments and deconditioning
