what are the 5 common signs of cancer
___/____ techniques were the most effective in awareness
media or marketing, public transit posters
about __% of Canadians will develop some type of cancer and cancer will be responsible for __ in __ deaths
about 50% of Canadians will develop some type of cancer and cancer will be responsible for 1 in 4 deaths
what is the difference between malignant vs benign tumours?
benign = non cancerous and can be dangerous only if their physical presence interferes with body functions –> cannot spread to other parts of the body
malignant tumour = cancerous and calls divide without control to provide an abnormal mass of cells –> can spread and invade other parts of the body
what is metastasis?
Metastasis is the spreading of cancer cells from one part of the body to another and occurs because cancer cells do not stick to each other as strongly as normal cells do and therefore may not remain at the site of the primary tumour
once cancer cells enter the ____ system or the ____ it is difficult to stop their spread to other organs in the body
lymphatic system, bloodstream
explain the stages of cancer
stage 0 = a precancerous change occurs
stage 1 = tumour is small and has not grown outside the organ it started in
stage 2 and 3 = tumour is larger and has grown outside the organ it started it towards a nearby tissue
stage 4 = the cancer has spread through the blood or lymphatic system to a distant site in the body (metastasis)
Mark has been noticing some cancerous symptoms such as a lump on the neck. He goes to the doctors and they find a tumour. However, the tumour is small and has not grown outside of the neck area. What stage of cancer could mark have?
stage 1
explain the types of cancer: 1. carcinomas 2. sarcomas 3. lymphomas 4, leukemias
- from epithelial tissues that cover external body surfaces or internal tubes–> most common type on the skin, breast, uterus, prostate, lungs and gastrointestinal tract
- from connective and fibrous tissues like muscle, bone, cartilage and membranes
- in lymph nodes which are the infectious fighting system
- cancers of blood forming cells normally in bone marrow
Peter has been diagnosed with a type of cancer. If the cancer is lining the gastrointestinal tract what type does he likely have?
carcinoma
