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

A single cancer cell will always result later in a tumor, lesion or mass? Does a cancer cell always multiplies with/without intervention?

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 more

What's the chance of pancrtic cancer they call it mass called lymphadenopathy at small bowl. All blood work is normal tumor markers normal to I am 36 f?

What's the chance of pancrtic cancer they call it mass called lymphadenopathy at small bowl. All blood work is normal tumor markers normal to I am 36 f?

Your question: Is rather disjointed perhaps because you are scared, but small bowel lymphadenopathy is not synonymous with pancreatic cancer which btw would be unusual at your age, mesenteric adenitis from a viral illness, non specific enteritis, or over-read of a ct scan is a little more common. Why don't you ask the doctor who ordered the ct scan on your behalf about the results. ...Read more

Can cancer or a brain tumor cause some sort of rapidly growing white/yellow mass/lesion in retina (spot in central vision)?

Can cancer or a brain tumor cause some sort of rapidly growing white/yellow mass/lesion in retina (spot in central vision)?

Retina: Anatomically the retina is an extension of the central nervous system, so spread from a CNS tumor that has access to the spinal fluid or the optic nerve may spread to involve the retina with little obstruction. ...Read more

Ct scan last summer showed no pancreatic mass. 1 yr later is a mass. Tumor markers high. Biopsy showed scar tissue. Is it still pancreatic cancer?

Ct scan last summer showed no pancreatic mass. 1 yr later is a mass. Tumor markers high. Biopsy showed scar tissue. Is it still pancreatic cancer?

Cancer: It is not pancreatic cancer unless and until to doctor and the pathology lab confirm you have pancreatic cancer.
If that is the case curative treatment can be performed and you would need other meds.
Hope all goes well. ...Read more

Are tumor and cancer the same thing?

Are tumor and cancer the same thing?

No: Tumor is a non-specific term for a swelling. Tumor may be benign or malignant. A malignant tumor is cancer.
Examples of benign tumors are fibroids, lipomas, and moles. Malignant tumors, cancers, are like breast or lung cancer.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex, if you have sex. ...Read more

How do a cyst and a cancer tumor differ?

Cyst is fluid filled: A cyst by definition is a fluid filled mass which is often benign. A tumor/cancer is typically solid in structure or mixture of solid material and fluid (Cystadenocarcinoma of ovary is an example).
An ultrasound examination is the best way to make a clear cut distinction. A CT scan is equally good test to define the nature of this lesion. ...Read more

What are signs and symptoms of a cancer tumor?

What are signs and symptoms of a cancer tumor?

Numerous: By definition a cancer is a growing lesion that has the potential to metastasize and has achieved immortality thru the production of telomerase. As such and depending on the structure involved a mass can be noted and symptoms such as obstruction, hemorrhage, pain and jaundice can be a result of the lesion. Weight loss and anorexia frequently follow. ...Read more

What is meant by "luminal type" cancer or tumor?

What is meant by "luminal type" cancer or tumor?

Often good prognosis: Molecular biologists can subtype breast cancers in many ways. One classification looks at luminal (phenobarbital) vs. Basaloid cells of origin. Each has specific molecular biology, but luminal (phenobarbital) types tend to have estrogen receptors and basaloid do not. Er+ tumors fare better. The susan g. Komen website explains this well in lay terms. Http://ww5.komen. Org/breastcancer/subtypesofbreastcancer. Html. ...Read more

Does low levels of tumor marker indicate no more cancer?

Does low levels of tumor marker indicate no more cancer?

Not necessarily: Tumor makers are good for monitoring the response to treatment. Low or better yet, absent levels may mean that tumor is not there, however, more often it indicates a remission and levels increase if there is a recurrence. Therefore low levels of tumor markers do not always mean "no more cancer". ...Read more

What are some tumors or cancers that causes hypothyrodism?

What are some tumors or cancers that causes hypothyrodism?

Secondary cause: Secondary hypothyroidism is due to a failure of the pituitary gland to release thyroid stimulating hormone (TSH) or thyrotropin releasing hormone (trh). This is usually caused by a tumor in the area of the pituitary or hypothalamus. Or, it can be caused by radiation to the brain. ...Read more

Why do people in Australia get so many skin cancers and tumors?

Why do people in Australia get so many skin cancers and tumors?

Sun exsposure: Because of excessive exposure to sun the country's 22 million people are 13 times more likely to develop skin cancer than the global average. It has the globe's highest rate of deadly melanoma and one of the highest overall rates of cancer. Australia's proximity to Antarctica, where there is a hole in the ozone layer that filters out UV rays may also increase the risk. There are also higher rates of detection and tracking that can explain the number of cases of cancer diagnosed each year. ...Read more

Will a biopsy be performed to make sure that the tumor is a cancer?

Blood tests: Tumor markers are blood tests that are sometimes used to follow progression of cancer once it has already been diagnosed. We rarely, if ever, use tumor makers to make a cancer diagnosis. There are many other reasons why these markers may be elevated including inflammation, infection, etc. ...Read more

Why am I getting chemo (tumor removed)when others with cancer do not?

Your Doc can explain: Chemo is often used after removing the tumors especially when the tumor is large or has spread into the nearby lymph nodes. You should ask your doctor the stage of your cancer, only then you can compare your case with anyone else's. The treatments are typically stage-based. ...Read more

Can you explain if it's possible to have a tumor that has cancer cells, but it's not cancer?

Can you explain if it's possible to have a tumor that has cancer cells, but it's not cancer?

Matter of definition: This has a lot to do with terminology. When one speaks about cancer cells, they are referring to abnormal cells that have abnormal chromosomes (mitoses) and increased number and invasiveness. There are criteria that are used by pathologists that determine if a tumor meets the criteria of cancer. Thus if the tumor has these cancer or malignant cells, then it is cancer. ...Read more

Neoplasms (Definition)

"tumor" literally translates as "mass", so even a fresh bruise could be called a "tumor". Doctors use the term "neoplasm" (tranlates literally as new growth) to describe tumors that are abnormal growths of cells. These may be benign or malignant; "malignant" = cancer. In everyday usage, we use "tumor" ...Read more
