are spindle cells always cancer?

I do not know alot about them, but I do know that spindle proteins are used in cell division to move the chromatids.\n\nSee http://www.scienceaid.co.uk/celldivision.html for more about cell division and spindle proteins.

No, it does not mean cancer but get it checked out.  Could be a boil, benign cyst, or many other harmless things.

You need to know what type of cancer cell.\nGlioblastoma Multiforme is one type...bad one...\nFind out what type and then do a medical literature search...pubmed...I don't know the web address but you can yahoo search it

Mitosis, also called karyokinesis, is division of the nucleus and its chromosomes.  It is followed by division of the cytoplasm known as cytokinesis.  Both mitosis and cytokinesis are parts of the life of a cell called the Cell Cycle.  Most of the life of a cell is spent in a non-dividing phase called Interphase.  Interphase includes G1 stage in which the newly divided cells grow in size, S stage in which the number of chromosomes is doubled and appear as chromatin, and G2 stage where the cell makes the enzymes & other cellular materials needed for mitosis.\n\nMitosis has 4 major stages --- Prophase, Metaphase, Anaphase, and Telophase. When a living organism needs new cells to repair damage, grow, or just maintain its condition, cells undergo mitosis.\n\nDuring Prophase, the DNA and proteins start to condense. The two centrioles move toward the opposite end of the cell in animals or microtubules are assembled in plants to form a spindle. The nuclear envelope and nucleolus also start to break up.\n\n\nProphase\n\nDuring Metaphase, the spindle apparatus attaches to sister chromatids of each chromosome. All the chromosomes are line up at the equator of the spindle. They are now in their most tightly condensed form.\n\n\nMetaphase\n\nDuring Anaphase, the spindle fibers attached to the two sister chromatids of each chromosome contract and separate chromosomes which move to opposite poles of the cell.\n\n\nAnaphase\nIn Telophase, as the 2 new cells pinch in half (animal cells) or a cell plate forms (plant cells), the chromosomes become less condensed again and reappear as chromatin. New membrane forms nuclear envelopes and the nucleolus is reformed.

Brain cancer, (generally glioma) is relatively rare, and this type of cancer, as far as I am aware, does not appear to run in families, as do certain breast cancers.  In case you are not aware, if you live long enough, you will die of cancer -- that is, if you do not die of heart problems, in child birth, in an accident, and so on.  In ancient times, though cancers were recorded, and documented by the Greeks, as well as the Egyptians, because the average life span was only in the 30's, cancers were less common causes of death than today.   So to answer your question, no, you are probably not at risk of getting this type of cancer.  My dad answered a question for me once when I was a kid (He was an MD.)  "  Daddy, how do I know I don't have a cancer?"  His answer, tongue in cheek, " Have an autopsy performed on yourself every six months."   You should be aware that we all have a cancer all the time -- that is, if we define cancer as a cell that has made a mistake and is multiplying beyond ordinary ways.  But our immune system recognizes the problem and destroys it.  As we age, the immune system is less reliable.  It is then that we get a cancer large enough to be found.  Helpful?

its just a rumor. Magnetism does not induce cancer. We live in a polarised world with a magnetic north and south.

No. Cancer is due to genetic changes (mutations) that develop in cells when they divide. Most of these changes get repaired at the cellular level but some are not. If the change makes the cell behave and grow abnormally then this is cancer. Lots of environmental factors increase the risk of mutations or genetic changes including toxins in cigarette smoke - this is why cigarettes cause cancer.

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.

The centrosome is definitely necessary for mitosis because the centrosome is the microtubule organising centre for the cell. All microtubules are generated from the centrosome.

My wife had one 3 years ago and doctors left it.  It turned out to be cancer and she is still fighting it. DO NOT HESITATE GETTING TREATMENT BECAUSE IT MAY COST YOUR LIFE AND YOUR KIDS WONT HAVE A MUM

Presumably you don't mean monosomy X? Monosomy 10 seems to be something associated with some types of tumor cells not with a genetic disorder at birth

Chances are likely it's not cancer related.  But at your next annual visit with your doctor you should mention it.  You should also be performing a self exam.\n\nMore likely than not, it's hormonal related and if you monitor it over the next few months you'll probably find a correlation with your menstrual cycle.  Pain occurs usually the same time within the cycle either before, during, or after.    It is extremely common.

Testicular cancer is one of the most common cancers in young men between the ages of 15 and 35, but the disease also occurs in other age groups, so all men should be aware of its symptoms. While testicular cancer is common among young men, young men typically do not develop any kind of cancer, so overall, testicular cancer is a relatively rare disease. This form of cancer is almost always curable if it is found early. Most testicular cancers are found by men themselves, either as a painless lump, a hardening or change in size of the testicle, or pain in the testicle. Children born with an undescended testicle have an increased risk of getting testicular cancer, regardless of whether surgery is done to correct the problem. However, the surgery should still be done to preserve fertility. The theory is that the increased risk of testicular cancer is due to whatever caused the undescended testicle, not just by the fact that the testicle was undescended.

There are a few main checkpoints before cell division which you might be thinking of. \n\nBetween G1 and S, in the middle of the S phase, and between G2 and M, all checking to make sure that any damaged DNA is repaired before replication/division.\n\nThere are also checkpoints during mitosis, for example, between metaphase and anaphase to make sure all chromosomes are attached to spindles.

well to be scientifically correct (i think but hey im 16 so what do i know) i think all of us have "cancer" cells when we are concieved, but i think it takes somethin to activate them, so really, technically speaking (refer to comment above) i think its when u are born..? but i know thats not what u asked so lets see, i knew a girl that got breast cancer (at least she found out about it) 2 months after she graduated from high school

All mammals can get cancer so the beluga whale is no different. Cancer is when something goes wrong with cell division.

Just FYI Pancoast tumors aren't always cancerous.  I know someone who just had one resected, and it was found to be fibrous tissue.  No cancer.  He didn't smoke either.
