What is small cell cancer?

What is small cell cancer?

Usually lung: This is a special kind of smoker's lung cancer that isn't curable but usually responds amazingly well for months to a few years to simple classical chemotherapy. The term "oat cell" describes its classic look. Small-cell cancers can pop up in other organs and often act similarly. ...Read more

Cancer (Definition)

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

Can small cell cancer recur?

Can small cell cancer recur?

Yes: Short answer: yes. Small cell lung cancer is staged as either limited stage (fits within a radiation field for treatment) or extensive stage. It tends to respond well to treatment, but recur. ...Read more

How can some cells become cancer?

How can some cells become cancer?

No short answer: Changes to dna is a final common pathway. Things we do (smoke, drink alcohol, obesity) can contribute. Environmental exposures ( toxic waste, radiation, excessive sun exposure) are also causes. Inherited gene mutations ( brca in breast, hnpcc in colon, men in endocrine tumors) confer higher than average risk for those families. Best to avoid bad things, and do screening tests at the right age. ...Read more

How can some cells become cancer?

How can some cells become cancer?

Genes & environment: Cancer arises from genetic changes in cells that lead to their uncontrolled growth. These changes arise from a complex interplay between our inherited genes and our environmental exposures. Hereditary cancers occur when defective genes are inherited, predisposing cells to become malignant. Environmental damage (smoking, hpv, radiation, diet) to cells also can cause these transformations. ...Read more

How is cancer related to cell division?

How is cancer related to cell division?

Mutation in p53: normal cells that divide have control over a mutation that arises. If so, the division is slowed by p53 so that mutations in DNA are repaired and not passed to next generation. In cancer the mutation in the p53 oncogene does not function to slow cell division for repair and the mutation is passed to next generation of cells. ...Read more

How does cancer affect cells in the body?

How does cancer affect cells in the body?

Invade organs: As the cancer grows it produces a proteinase that allows for invasion of blood vessels. It breaks down -e-cadherin to s-ecadherin that allows metastasis. The spread is predetermined by the surface protein on the tumor cell. Once spead to an organ occurs it can grow in that organ and in many instances can destroy the organ function such as liver If TNFproduced cacchexia occurs. ...Read more

How does cancer develop? In cells or what?

How does cancer develop? In cells or what?

Multiple steps: Cancer is multi-step process of accumulating defects in the genome of the cells exposed to various insults, including inherited damage. The changes often start by facilitating the growth of cells and additional damage to the cells accrues that enables them to grow unchecked, acquire the ability to invade and metastasize. A human cancer has about 90 genetic defects. ...Read more

Which part of the cell does cancer affect?

Which part of the cell does cancer affect?

DNA: Cancer results from mutations or defects in a cells dna. This in turn can effect multiple parts of the cell but predominately causes problems because the cell does not know when to stop replicating (multiplying). ...Read more

Could different cancers have different cells?

Could different cancers have different cells?

Absolutely: Cancer cells are different in their microscopic appearance, behavior, and genetic characteristics, not only between different cancers but sometimes within the same cancer. That is one main challenges of cancer therapy, one therapy does not always kill all the cells due to their heterogeneous nature. ...Read more

Can you have non-small and small cell cancer at the same time?

Can you have non-small and small cell cancer at the same time?

Yes: Non-small cell lung cancer (nsclc) and small cell lung cancer (sclc) are two different types of lung cancer. They can occur together at the same time. Not very common, but it happens. Some of the same chemotherapies (and radiation) may be effective against both types of tumors. ...Read more

Can you tell me how could p53 and p21 work in cell cylce/cancer?

Tumor suppressors: P53 has many 'anticancer functions': it can activate dna repair proteins when dna has sustained damage. It can arrest growth by holding the cell cycle at its start. It can initiate apoptosis (programmed cell death) if dna damage proves to be significant. P21 is generally controlled by p53. P21 can cause cellular growth arrest preventing cellular proliferations. Hope this helps. ...Read more

What are potential reasons for cancer development in dividing cells?

What are potential reasons for cancer development in dividing cells?

Mutations: Dividing cells undergo dna synthesis and production of new cells. During this process there is always potential for errors in dna replication. Some errors lead to uncontrolled growth and cancer development. ...Read more

How long does it take for precancerous cells in your body to become cancer?

Varies: You start acquiring the mutations that produce cancer when your life starts. Cells that a pathologist can tell are "precancerous" signal "time for treatment". Cases in which the mildest of dysplasias of the cervix have turned to invasive cancer in less than a year are well known. Others simply disappear, or never progress. Be glad for early detection -- and congratulations on a likely cure. ...Read more

I am curious if cancers are just rogue cells how are there different types?

I am curious if cancers are just rogue cells how are there different types?

Here's why: Each type of cell in our bodies -- and there are a couple of hundred subtypes -- gives rise to several different types of cancer, based first on what's caused the cell to differentiate in the first place. Cancers are of course driven by accumulated mutations that make the cells "rogue" (if you like), prone to overgrow and invade. Each named cancer typically carries different mutations. ...Read more

Could you tell me what happens to the cells that can trigger cancer to develop?

Let's try this..: Simply put, human cells have a "self-destruct" key that kills the cell when it mutates (apoptosis.) when that system fails, the mutated cells begin to grow and replicate outside the normal boundaries of the human system. Those mutated cells rob the healthy system and grow unfettered - a cancer. I hope this helps. Good luck. ...Read more

What causes any type of cancer? I know it's cells dividing uncontrollably but why does that happen?

What causes any type of cancer?  I know it's cells dividing uncontrollably but why does that happen?

Mutations: A clone of cells has acquired, through natural selection, several genetic mutations each giving an unfair growth advantage over the neighbors. When the genome itself has become destabilized, more mutations accumulate rapidly & the cells recovery the primitive ability to invade and spread. The best way to whether a "pop" cancer-cause claim could be valid is if the exposure is a powerful mutagen. ...Read more

I had moderate pretty cancerous cells almost 2 years ago. If left untreated what are the chances of it turning to cancer?

Why take any?: It is not feasible to give an estimate of the risk. I take it you are talking about uterine cervix. Please see your doctor for follow-up. If you cannot afford one, check with your city or county health department or local chapter of Planned Parenthood (they provide more than abortions!). ...Read more

Can cell phones cause cancer?

Can cell phones cause cancer?

No strong evidence: The studies out there show that there could be some risk of cell phone and development of glioma , but the evidence is not strong enough to confirm the link, and needs to be researched further. It is definitely raise a concern, but there is no conclusive relationship. So, use an ear piece and don't let / limit your children use cell phone. ...Read more
