What happens if skin cancer is left untreated?

What happens if skin cancer is left untreated?

It will spread: Different cancers spread differently. All cancers will grow locally and cause damage to nearby structures. Cancers can spread to lymph nodes which drain a particular body area as well (i.e. Squamous cell, and melanoma). Some cancers (particularly melanoma) will jump to distant sites early (brain, lung, liver, etc). This is distant metastasis, and imparts poor prognosis. ...Read more

What happens if cancer metastasis to the lungs?

What happens if cancer metastasis to the lungs?

Tumors can: Go to the lung substance, or to the lining of the chest cavity. As the tumor expands or fluid accumulates, it crowds out the abilty of the lung to do its job, and shortness of breath, oxygen starvation occurs. Removing fluid, and treating with systemic therapy can slow progresson. ...Read more

What happens if a squamous cancer goes untreated?

Various developments: If lesion small and cutaneous, then lesion will grow, ulcerate and scab over. If aggressive skin lesion on face or chest wall such lesions rapidly metastasize to region nodes such as those of parotid or axilla and then require radical node dissection. Have seen cases where a chest wall lesion metastatic to axilla required amputation secondary to major vessel involvement. ...Read more

What happens if no chemo .. what is it like for someone to die from lung cancer?

Comfort care time: If someone has advanced lung cancer and treatment is not an option, then the focus should be on making sure any symptoms they have or may develop will be controlled.

There may be constipation from pain medications/lack of appetite. ...Read more

What are odds for surviving bladder cancer? The doctor says the bladder cancer is in early stages. Does this mean it can be cured?

Bladder cancer: Early stage bladder cancer can nearly always be successfully treated without major surgery. It is important to follow the surveillance cysto protocol after initial cystoscopic treatment (resection) due to the tendency for superficial recurrences. Cure is a relative term when dealing with some cancers. ...Read more

What happens when osteosarcoma spreads to a lung? Is the tumor treated in the lungs?

What happens when osteosarcoma spreads to a lung? Is the tumor treated in the lungs?

Depends on extent: Osteosarcoma is found in the lungs as metastatic disease during initial diagnosis or at relapse/ progression of disease. Lung mets that are isolated or limited in number might be able to be removed surgically. Additional chemotherapy would then be needed afterwards in an attempt to prevent further recurrence. However, lung involvement is an ominous finding. ...Read more

What happens if the bone tumor is detected as cancerous then what is the probability that she will recover with medicine?

What happens if the bone tumor is detected as cancerous then what is the probability that she will recover with medicine?

Depends on primary: Depends what the primary site causing the metastasis is. When tumors of the lung spread to bone, even with standard chemotherapy, the prognosis is poor though improving with some of the immunologic agents like the PD-1's. With breast cancer to bone, most patients receiving hormone therapy or chemo if triple negative can survive for 10 yrs. ...Read more

What is metastasis and at what stage during the devolopment of lung cancer does it start to occur?

The molecular changes in the tumor associated with ability to metastasize vary with different tumors and are not clearly defined. In some types of lung cancers, metastases can occur even before cancer becomes detectable by x-ray. ...Read more

What exactly is it that causes lung cancer. Is it the nicotine, the tobacco, or the smoke?

What exactly is it that causes lung cancer. Is it the nicotine, the tobacco, or the smoke?

The smoke: It is the smoke that causes the lung cancer. The smoke causes an intense inflammatory reaction in the lungs, and when this continues for years and years, it can cause lung cancer. Now, the nicotine itself doesn't usually cause the cancer, but it is more addictive than heroin. Thus, you get hooked on the cigarettes, which have the smoke, which causes the cancer. A very, very sinister product. ...Read more

What happens if recurrent bile duct cancer has spread to the bone it is difficult to treat?

Very difficult: Bile duct cancers behave in a similar fashion to pancreatic cancer. When localized to the common duct and resected, the patient has a chance, especially post RT with gemcitabine. When the tumor spreads to bone Im not sure that combo chemo with any of the available monoclonal can demonstrate any effect on survival. ...Read more

What is the main reason of Ascites?? Is it deadly? or lead to cancer?

Belly fluid: Ascites is a term used to describe fluid collecting in the abdomen. it can happen for many different reasons. How "deadly" or bad ascites can be really depends on the reason behind it and whether the fluid in the belly ever gets infected. A common reason fluid builds up is liver disease. This happens because the liver is responsible for making things that keep fluid from leaking. Good luck! ...Read more

Two Ways: Bone marrow transplants help cure aggressive leukemia in two ways. First, it allows doctors to give high dose chemotherapy and sometimes total body radiation therapy therapy that have a higher chance of killing every last leukemia cell. Second, it essentially gives the patient a new immune system that will hopefully recognize and kill any remaining leukemia cells. ...Read more

Lung (Definition)

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
