Tumors grading and staging
| Question | Answer |
|---|---|
| Grading | determining the degree of anaplasia (How similar it is to origin tissue |
| carcanoma | Originate in the epithermal |
| Grade 1 | Tumor cells are well differentiated, closely resembling normal parent tissue |
| Grade 2 | Tumor cells are intermediate in appearance, Moderately or poorly differentiated |
| Grade 3 | Tumor cells are very abnormal and poorly differentiated |
| Grade 4 | Tumor cells are so anaplastic that recognition of the tumor's tissue origin is different |
| Staging Neoplasms involves | estimating the extent to which the tumor has spread. |
| T Staging refers to | the size and extent |
| Curative | Full removal of cancerous cells |
| Palliative | Making them comfortable not curable |
| Preventative | Attempting to stop the cancer before it starts |
| Debulking | Surgery that removes as much of a tumor as possible without destroying organ/tissues nearby |
| N Staging refers to | The number of area lymph nodes involved |
| M Staging refers to | any metastasis of the primary tumor |
| TX | Tumor cannot be measured (It cannot be found) |
| T0 | No evidence of tumor |
| Tis | Carcinoma in situ (Limited to superficial layer of tissue) |
| Mohs | Removal of cancerous skin layer by layer |
| Electrocautery | Burning of cancer tissue with electric current. |
| Laser surgery | a powerful light source to cut through tissue or to vaporize cancers of the cervix, larynx, liver, rectum, or skin |
| Hyperplasia | Rapid growth of cancerous cells |
| Dysplasia | Abnormal growth of cancerous cells |
| Carcinoma in situ | Limited to superficial layer of tissue |
| Metastasis | How it spreads |
| Stage 1 | Hyperplasia |
| Stage 2 | Dysplasia |
| Stage 3 | Carcinoma in situ |
| Stage 4 | Metastasis |
| Carcinogens | Substances that can increase the risk of cancer development |
| Staging Cancer | Estimates the extent to which a tumor has spread |
| Sarcomas | Arise from supportive and connective tissue |
| Precision medicine | AKA personalized medicine based on genectic understanding of a patient's disease. |
