Non-specific, Generalized Signs and Symptoms of Cancer include pain, fatigue, a lump or area of thickening that can be felt under the skin, weight changes, skin changes, changes in bowel or bladder habits, and persistent cough or trouble breathing.
Patient self-report is the single most reliable indicator of the existence and intensity of acute pain and any concomitant affective discomfort or distress.
Pathologic classification of tumor is used to define the type of tissue from which the tumor originated and the degree to which the tumor cells retain the functional and histologic characteristics of the tissue of origin, known as differentiation.
Secondary prevention of cancer involves screening and early detection activities to identify precancerous lesions and early-stage cancer in individuals who lack signs and symptoms of cancer.
Samples of cells used to establish the tumor grade may be obtained from tissue scrapings, body fluids, secretions, washings, biopsy, or surgical excision.
Tertiary prevention of cancer involves health counseling and chemoprevention strategies to monitor for and prevent recurrence of the primary cancer and screen for the development of second malignancies in cancer survivors.
Primary prevention of cancer involves health promotion and health protection strategies such as health counseling, cessation of smoking, limiting alcohol intake, diet, exercise, and immunization.
Grade IV tumors do not clearly resemble the tissue of origin in structure and are associated with poor differentiation, poor function, and are often more aggressive and less responsive to treatment.
Tumor Marker Identification involves the analysis of biochemical mediators found in tumor tissue, blood, or other body fluids that are indicative of cancer cells or specific characteristics of cancer cells.
Fine-needle aspiration biopsy (FNA) is a procedure where cells are aspirated through a needle and the specimen can only be analyzed by cytologic examination.
Distant metastasis (M) stage includes Mx, M0, M1, M2, M3 which indicate the ascending degree of distant metastasis, including metastasis to distant lymph nodes.
Carcinoma in situ is a group of abnormal cells that have not spread from the location where they first formed, although they may later spread into normal tissue and become cancer.
