What Is The Difference Between Stage And Grade Of Lung Cancer
A lot: Stage refers to extent of cancer: generally stage 1 & 2 are early cancers; stage 3 involves spread to the nodes or structures in the middle of the chest; stage 4 involves spread to both lungs or other organs. Grade refers to the degree of abnormal appearance of the cancer when seen under the microscope- usually grades range from 1-3. ...Read moreSee 2 more doctor answers
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
Grade is key.: Brain tumors are rated by the world health organization grade, with higher grades generally being more aggressive. Stage is a terminology used in cancers outside of the brain, which describe how much a cancer has spread all over the body. Because brain tumors/cancers generally do not spread all over the body, we rarely use "staging" with primary brain tumors. ...Read moreSee 1 more doctor answer
3b is more advanced: Although both stages are serious, stage 3b tends to have more severe lymph node spread, usually meaning spread out side the affected side of the chest to the collar bone, neck or lymph nodes in the opposite chest. The 5 year survival with 3a is 20-25%, with 3b is 10%. ...Read moreSee 1 more doctor answer
Different things: Emphysema is destruction of lung tissue from (most often) smoking. Lung cancer is an abnormal growth of lung tissue that can cause destruction of many tissues, not just lung. They are completely different diseases. But, because the most common cause of lung cancer is smoking, many times patients with lung cancer have emphysema and vice versa. ...Read moreSee 1 more doctor answer
Different cancers: Sarcomas are very rare cancers that arise from bone, muscle, nerves, blood vessels or other connective tissues. Carcinomas are very common cancers that tend form glands. Most common examples are breast cancer, lung cancer, colon cancer, prostate cancer and renal (kidney) cancer, among others. ...Read moreSee 1 more doctor answer
Good question!: Stage describes how spread a cancer is. Usually, but not always, it goes from stage 1 (or 0 in some cases) to 4. Grade has to do with how the cells look under the microscope. The more they look like normal cells, the better. Both high stage and high grade usually mean worse prognosis but they do not always go together. You can have a high grade, low stage cancer or viseversa. ...Read more
Different: Non small cell lung cancer mainstay of therapy is surgical resection for appropiate lesions. 5yr survival for stage i nsclc after surgical resection is about 70%, stage ii about 30%. Chronic lung disease is emphysema, bronchitis, asthma, obviously a totally different diagnosis. Patients may develop lung cancer with or without chronic lung disease but more common in smokers. ...Read moreSee 1 more doctor answer
Definitions: A tumor is a general term for a lump or mass in any location in the body. It can be cancerous or noncancerous. Breast cancer refers to malignant cells found in the breast. There are many benign/noncancerous tumors that can be found in the breast. Usually a needle biopsy is performed to determin if cancer is present. ...Read moreSee 1 more doctor answer
Different tumors: , Sarcomatoid mesothelioma is the least common of the disease’s three main histological cell types: epithelioid, sarcomatoid and biphasic. This type has been called sarcomatous, diffuse malignant fibrous and spindled mesothelioma. It accounts for 7 to 20 percent of all mesotheliomas . The cells appear elongated,and spindle-shaped.The Sarcomas in general are a broad spectrum of malignant tumors arising in supportive tissue such as muscle, bone, nerve and blood vessel tissue. They are unrelated to the mesotheliomas ...Read more
Great difference: The precancerous conditions which are believed to lead to cancer cannot spread beyond the superficial layer of the cervix. None of these precancerous conditions leads to cancer 100% of the time, but the worse they are, and the older the patient is, the more likely it is that cancer will develop. The point of pap smears is to detect the precancerous conditions so they can be removed. ...Read moreSee 1 more doctor answer
Different tumors: Over 90% of testis tumors are germ cell tumors which are seminoma, non-seminoma or mixed depending on the type of malignant cell. Classic seminoma is the most common testis tumor in adults. Almost all testis tumors are initially treated by surgical removal (orchiectomy). Then, based on the type of tumor and stage (aggressive characteristics, spread to lymph nodes) determines next treatment. ...Read moreSee 1 more doctor answer
Cancer v. Node: Lymph node is a structure in the body that screens lymph that is being drained from surrounding tissue against infection. Breast cancer is a collection of cells from breast ducts/lobules (usually) that have become immortal and often rapidly proliferative whereby they invade surrounding tissues depriving normal cells the ability to co-exist. Cancer cells may find their way to nearby lymph nodes. ...Read moreSee 2 more doctor answers
Survival, but.....: Used to be, the short answer was simply survival risk with stage 1 having the best prognosis and stage IV the worst. While stages 1/2 still have the highest survival rates but improved surgical techniques and chemotherapy and i'd add lifestyle changes, have leveled the playing field greatly. Colon cancer, even advanced is often quite treatable. ...Read more
Location, Incidence: Colon cancer arises from a site involving the large intestine commonly called the colon (ascending, transverse, descending, sigmoid). Intestinal cancer usually refers to small intestinal cancer that arises from the duodenum, jejunum or ileum. Colon cancer is much more common compared to cancer arising from the small intestines which is considered rare. ...Read moreSee 1 more doctor answer
Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
