Difference Between Cancerous Lung Tissue And Normal Lung Tissue
What can I do if my dad has kidney cancer and has started coughing up lung tissue. What can I expect?
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
Bronchoscope Dr said No cancer this am so what could it be if Hiler mass & Mediastinal Lymphadenopathy in lung?Tissue sent out after pathologist check
COPD versus cancer: In emphysema the air sacs of the lung (alveoli) are damaged. The result is the lung "traps air in the damaged sacs and it becomes hard to exhale. The lung becomes over inflated. Breathing (getting oxygen in and carbon dioxide out) are progressively harder. In lung cancer a cell is damaged and can not regulate its growth, ( ie becomes cancerous) with tumor formation. Both are linked to smoking. ...Read more
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 more
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 more
Everything: Small cell lung cancer is almost completely different than non small cell- the only thing the same is that it is located on the lung and may give the same symptoms. They are different in molecular biology level, they look and behave differently. Small cell behaves more agressive- like systemic disease even from the first presentation; have different treatment and prognosis .D/w your oncologist. ...Read more
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 more
Different cell types: lsmall cell cancer of the ung is a neuroendocrine tumor responding to chemo such as the adriamycins (doxorubicin). Non small cell cancer represents the adenocarcinomas and squamous cell cancers requiring a different groujp of drugs that usually include the platinums and the newer monoclonal antibodies. ...Read more
Whats the difference between lung cancer and a TMJ disorder and how can I be absolutely sure I have either of these things?
Not related: Lung cancer usually presents with new onset coughing or coughing up blood. A chest x-ray or ct may show a mass in the lung or lymph nodes in the chest. Diagnosis requires a biopsy, often via a bronchoscope (look into bronchial tubes) or with a ct guided biopsy. Tmj is a dysfunction of the temporomandibular joint and can cause pain on opening or closing the mouth-no association with lung cancer. ...Read more
Doctors, what is the difference between advanced testicular cancer and another advance cancer such as advanced lung cancer?
More curable: Advanced testicular cancer spreads to nodal area. In most instances the primmary is resectable and nodes can most oftern be removed. These tumors are sensitive to radiation and chemotherapy with a high cure rate. Lung cancer when advanced is most often not resectable and invades major pulmonary vessels into pericardium. Effective radiation hard to deliver and chemo limited. ...Read more
Is it easy for doctors to tell the difference between calcified nodule in the lung and lung cancer mass ? And what is average age for non smoker?
Breast & Lung Cancer: Breast Cancer and Lung Cancer arise from different parts of the body. Breast cancer almost always arises from the ducts of the breast. Lung cancer usually arises from the lining of the lung. The two cancer have different natural histories. Breast cancer may metastasize or spread to other part of the body, including the lungs ...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 more
I was a heavy smoker from the age of 20 to 37. I quit three years ago, am now 40. Lung cancer has run in my family with lifelong smokers. Does quitting really make a difference with a familial history as far as cancer incidence?
Can any doc tell me what's the difference in small cell lung cancer and non-small cell lung cancer?
Cells and treatment.:
The cell types and treatment is the biggest issues. Non small cell are adeno, large and squamous cell types. Each have an association with smoking but not always. Treatment is the same. First if possible resection +/- chemo/radiation. Cure can be resection.
Small cell=smoking. Can be limitted or extensive. Responds well to chemo. Grows faster, mostly treatable not cureable. Need to talk to ur md! ...Read more
Why would a MRI be better at finding mesothelioma and a ct scan better at lung cancer or is there no difference for the 2?

It's possible: There is precedence for scar turning into cancer. On the skin, long-standing scars can develop cancer so it's not out of the realm of possibility. Chronic irritation can contribute to changes. Usually it works in the opposite direction; cancer can mimic scar tissue and may not be diagnosed unless it grows. ...Read more
Positive margin: If a patient had early stage cancer that surgery would be the definitive treatment, but after pathology comes back showing a positive margin then radiation would be used without chemotherapy. However more adverse findings such as nodes would mean chemotherapy is necessary. ...Read more
After 2 chest xrays should I still worry about lung cancer? Both were normal and i just turned 38
Risk of lung cancer: If you are a nonsmoker and young, there is a small but not zero chance of developing lung cancer. The two negative chest xr should put your mind at ease. A chest xr is one way of detecting lung cancer but if you are a smoker 2packs perday for >10 years a screening ct scan of the lung is better for the higher risk patient. ...Read more
Can localised 2nd degree contact burns on ribcage (metal rod 20 second contact) damage underlying lung tissue?
Highly unlikely: It depends on if there is any other trauma with the impact of the rod, but a 2nd degree burn itself should not cause any damage to the lung. A 2nd degree burn by definition is only a partial thickness injury to the skin only, so you should have no worries. ...Read more
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
The body is composed of tissue that are classically described as beiing derived from three basic embyonic layers known as the endoderm, mesoderm and ectoderm that then differentiate into the structures that compose the body such as skin, soft tissues, bone, muscle, organs, etc. Stem cells are not differentiated and have the potential to ...Read more
