What Does A Cancer Cell Look Like
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
Different things...: Squamous cell skin cancer (scca) can take different appearances. In general the lesion will progressively enlarge. It is usually scaly and dry appearing and can have ulceration. It may bleed, esp. If picked at. It may be painless or itch. Early ones usually don't hurt. There are some benign skin lesions which mimic scca. Have any suspicious lesions examined and/or biopsied. ...Read moreSee 2 more doctor answers
A single cancer cell will always result later in a tumor, lesion or mass? Does a cancer cell always multiplies with/without intervention?
Nobody really knows: I would say NO. Surely many individual cancer cells die or don't reproduce, for any number of reasons. Suppose there are 37 trillion cells in the human body (like some websites say). Even if only one in 3.7 billion cells turned cancerous, that would be 10,000 cancers cells... and nobody walks around with that many tumors. That suggests cancer cells must be dying or failing to multiply. ...Read moreSee 1 more doctor answer
Are people ever misdiagnosed with having cancer of any type? Do all cytologists always agree on what a bad cancer cell looks like?
Yes...and no.: Yes misdiagnosis can happen. Cytology is the review of cells in fluid. This gives the pathologist much less to examine than a biopsy of tissue. A diagnosis based on cytology alone can be tricky in some cases (but not all). There is some degree of subjectivity in any visual examination so no, cytopathologists do not always agree. Second opinions are important and can always be requested! ...Read more
Man, there are : ..Entire books meant to answer that. Cells have instructions in their dna that establish their behavior. Sometimes those instructions are changed (mutations) and the cells start dividing too much, "learn" how to spread, and bypass their "self destruct" mechanisms. That ultimately leads to a malignancy. It is way more complicated that that but i ain't got space. Try the acs or the nci websites. ...Read more
This is surprisingly: Complex question. How long it takes for a mass to achieve a given size is highly variable and depends upon the rate of cell cycle progression, growth fraction (% of cells in the tumor that are dividing), rate of cell death that balances emergence of new cells, etc. Some cancers grow rapidly (eg., burkitt lymphoma) while others may take years to achieve comparable size. Why do you ask? ...Read more
No: Waves can cancel one another, and antidotes neutralize poisons, but there are no anti-cancer cancer cells. This is the stuff of you're living in the 21st century and you owe it to yourself to become scientifically literate -- many of your neighbors are not. Use that inquiring mind to understand how your body actually works and how disease really happens. ...Read moreSee 1 more doctor answer
How rapidly can a cancer cell grown in tissue cultures divide, and would that be the same rate inside your body?
Rare: . Malignant mesenchymomas are rare soft tissue tumors of mesenchymal origin. A case of pleural localization with liposarcomatous was noted which represents fibrous type of lesion combined with a malignant liposarcoma. Similar combinations has been seen but very uncommon ...Read more
