what are sarcoma and carcinoma?
961343
Types of cancer.\n\nA sarcoma is a cancer of the connective or supportive tissue (bone, cartilage, fat, muscle, blood vessels).\n\nCarcinoma is any cancer that arises from epithelial cells. It is malignant by definition: carcinomas invade surrounding tissues and organs, and may spread to lymph nodes and distal sites (metastasis).

Cancer, in laymans's terms, is the unregulated growth of a cell.  Now cell growth, and activities in general, are typically regulated through cell receptors which, in response to a stimulus, activate or release a kinase.  These kinases transfers phosphates to other proteins or phosphorylates them making them active to stimulate DNA replication and transcription (growth).  Cancer is commonly characterized by high levels of (active) kinase due to suppressed phosphotase activity (opposite of a kinase) or defective oncoreceptors stuck in the "ON" position.

Cancer looks like a spider. That's why it's named Cancer. Anyways, if you want to know how cancer actually happens I'll fill you in: You see if in some part of your body cell division gets out of control and too much Mitosis happens( mitosis is the sort of cell division that cells have but meiosis only happens in sexual organs) all the cells that are produces will start making a tumor. So, if this tumor is not that dangerous nothing will really happen. Although if it's not a good tumor, after a while the membrane of that tumor will tare apart and the cells will go to an organ of your body (where they are) and make the cancer although if they enter your blood things will get really dirty and they can go to all your organs.

Cancer is a condition that occurs when the cells in a person's body don't divide correctly--they don't stop dividing, in fact.  This causes a tumor in the area where the cells are multplying, which can be pretty much anywhere (lung, liver, stomach, breast, testicles, mouth, brain, cervix, skin, etc.).  The cancerous cells in the tumor can spread it to other areas in the body, in a process called metastasis.  \n\nYou can read more about cencer here:\nhttp://cancer.about.com/od/newlydiagnosed/a/whatcancer.htm\nIt doesn't have a lot of medical jargon and gives a lot of good information.\n\nHope this is helpful :-)

Cancer cells originate among the normal cells of the tissue or organ in which the cancer arises.  Some combination of external factors, e.g. carcinogenic chemical exposure, and a cell's response to those factors produces a cell that is genetically different from its normal neighbors.  It has become a mutant, containing altered DNA.  The most important result of this mutation is that the transformed cell escapes from the controls that regulate the growth, maturation, and rate of replication of its normal neighbors.  The transformed cell begins to grow more rapidly and divide at more and more frequent and irregular intervals.  The developing cancer becomes a cluster of deviant cells that consume more and more metabolic resources (nutrients and oxygen), depriving surrounding cells of these resources.\n\nAs this is happening, the malignant cells come to resemble their original cell type less and less.  Among other things, they will begin to produce plasma membrane proteins that differ from those of their normal precursors.  Often this occurs early enough in the course of the cancer development that the malignant cells can be recognized as foreign by the body's immune system and destroyed before they have a chance to develop into an actual tumor.  Many cell biologists believe that this process, the emergence, detection, and destruction of early incipient malignancies, begins to occur very early in life.  Part of the reason that clinically significant cancer becomes so much more frequent as we age is probably that this immune surveillance for abnormal cell development loses its effectiveness with age.\n\nCancers arising in different tissue types, and even in the same tissue types, vary widely in how much their cells are altered morphologically and phsyiologically from the original precursor cell type.  They also vary widely in how fast they grow, how early in their development they begin to invade and damage surrounding tissue, and how readily they colonize other tissues/organs via the bloodstream or the lymphatic circulation (metastasis).  Cancers in which the cells more closely resemble their precursors, which grow relatively slowly, and metastasize rarely or not at all, are usually easier to treat medicallly or surgically once they have been detected.  Cancers whose cells have been radically altered from the original cell type, which grow rapidly, and metastasize early, are much more difficult to treat and are more likely to be lethal.  This is especially true of cancers that grow to large size and metastasize before they even begin to produce symptoms noticeable by the patient.  Examples are most lung cancers, pancreatic cancers, and stomach cancers.\n\nIn any case, cancer cells differ greatly from their normal neighbors, most critically in the structure of their DNA and in the ways that the genetic information contained in their DNA is expressed.  The key result, again, is the abililty of these cells to grow and reproduce more rapidly and uncontrollably than their normal precursor cells.

There are several types of soft tissue sarcoma. Generally speaking the tumor is removed first with wide borders, then the oncologist decides if you need additional radiation treatment or chemo. Here is a link to the NIH web page so you can look up the exact info for whatever type soft tissue sarcoma you need to learn about.\n\nhttp://www.nlm.nih.gov/medlineplus/softtissuesarcoma.html

cancer is the most common cause of death of all animals.  cancer has been here since the dinosaurs.  there are cancer tumors in the dinosaur bones.  cancer is more a process than a disease.  After saying all that stomach cancer is a terrible condition and i hope you are just curious.

CLASSIFICATION OF CANCERS\nCarcinoma: malignant tumors derived from epithelial cells. This group represent the most common cancers, including the common forms of breast, prostate, lung and colon cancer. \nLymphoma and Leukemia: malignant tumors derived from blood and bone marrow cells \nSarcoma: malignant tumors derived from connective tissue, or mesenchymal cells \nMesothelioma: tumors derived from the mesothelial cells lining the peritoneum and the pleura. \nGlioma: tumors derived from brain cells \ngerm cell tumours: tumors derived from germ cells, normally found in the testicle and ovary \nChoriocarcinoma: malignant tumors derived from the placenta

there are a few different kinds of bone cancer.  leukemia is not one of them.  some examples:  osteosarcoma and ewing sarcoma\n\nosteoma is another non-cancer.  it's a benign tumor of the bone

Merkel Cell carcinoma is a very serious skin cancer because of the high chance of recurrence. Early treatment is essential and consists of surgical excision with wide margins to reduce the chances of recurrence.  It is as life threatening as melanoma. good luck\n\nhttp://cancerweb.ncl.ac.uk/cancernet/210847.html\n\nhttp://www.merkelcell.org/

A secondary neoplasm is an appearance of cancer, but not the primary cancer.  So, for instance, someone who has breast cancer, is told 3 months later that the cancer has spread to the liver.  The breast is the primary location, and the liver is the secondary.\nSimilarly, it can be said that the liver cancer is a secondary neoplasm, although it did not spread from the breast.  It is just another appearance of cancer in the body.\n\nHope this helped

An adenocarcinoma is a cancer that begins in a glandular organ, such as the stomach, gallbladder, kidneys, liver, etc. There is adenocarcinoma of "name your organ", and there is adenocarcinoma of an unknown primary, meaning they do not know what organ it originated from, which makes it very hard to treat. \n\nMetastatic cancer is one that has spread to other organs or lymph nodes. Non-metastatic cancer is one that has not spread and is contained in the originating site.

Do you mean Angiosarcoma? Angiosarcoma is extremely rare . It's a type of cancer that originates in the cells that line blood or lymph vessels.\n\nAngiosarcoma is also sometimes known as Cardiac Sarcoma when it begins in the heart.

Carcinoma is a new growth or metastaic tumor ...squamous cell cancer is most often a deadly carcinoma....Ummmm.  Whomever has these cancers should be under the care of an oncologist...if treatment is available, the specialist will know it.  It doesn't sound too promising for cure or longevity.  Let the oncologist guide the person dealing with these cancers....This is not the place to do it.  Sorry.

Cancer is characterised by mutations in genes that lead to uncontrolled cell growth, dvision and differentiation. Mitosis plays a great role in cancer development in that the cancer cells divide by mitosis, where the the daughter cells are diploid. Meiosis is another kind of division carried out in gametes (sperm cells and egg cells) where a daughter cell is haploid. So, somatic or body cells where cancer is developing divide in an uncontrolled manner by mitosis.

Adult brain tumors are diseases in which cancer (malignant) cells begin to grow in the tissues of the brain. The brain controls memory and learning, senses (hearing, sight, smell, taste, and touch), and emotion. It also controls other parts of the body, including muscles, organs, and blood vessels. Tumors that start in the brain are called primary brain tumor.its based on where the tumor is located.
