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

Is brachytherapy helpful for a prostate cancer patient who has metastasized cancer cells?

Is brachytherapy helpful for a prostate cancer patient who has metastasized cancer cells?

No.: Brachytherapy is used in the treatment of localized prostate cancer, or cancer that has not spread outside of the prostate gland. If a patient has metastatic disease, treatments need to be systemic, with the aim of halting the growth & spread of the cancer throughout the body. These treatments include hormonal therapy, chemotherapy, and immunotherapy. Urologists & medical oncologists can help. ...Read more

I'm concerned about prostate cancer metastasis. Where can prostate cancer spread?

I'm concerned about prostate cancer metastasis. Where can prostate cancer spread?

In theory, prostate cancer cells can spread anywhere in the body: In practice, though, most cases of prostate cancer metastasis occur in the lymph nodes and the bones. Prostate cancer metastasis occurs when cells break away from the tumor in the prostate. The cancer cells can travel through the lymphatic system or the bloodstream to other areas of the body. More commonly prostate cancer metastasis can occur in the: Bones, Lymph nodes, Lungs, Liver, Brain. Rare locations of prostate cancer metastasis include: Adrenal glands, Breasts, Eyes, Kidneys, Muscles, Pancreas, Salivary glands, Spleen. If you've been diagnosed with prostate cancer and you're concerned about prostate cancer metastasis, talk with your doctor about your risk of prostate cancer metastasis and your treatment options. ...Read more

Please explain: 5 CM irregular splenic lesion. Differential diagnosis lymphoma and splenic metastasis. Could this be cancer?

Please explain: 5 CM irregular splenic lesion. Differential diagnosis lymphoma and splenic metastasis. Could this be cancer?

Yes: Both are forms of cancer. It could also be a benign hemangioma, an epidermoid cyst, an infart (how's your overall vascular health?) or any of a number of other entities. What to do next will depend on your history and physical exam. You're in no immediate danger but this very much needs to be followed up. Many of the lymphomas especially are very curable with today's biotech. ...Read more

What negative health consequences are associated with cancer radiation and/or cancer surgery?

What negative health consequences are associated with cancer radiation and/or cancer surgery?

Depends on type.: Cancer treatment is usually divided into local (the organ where the cancer started) and systemic (the rest of the body) therapy. Both surgery and radiation therapy are local rx's--their side effects are dependent on which organ is being treated. Which specific cancer type are you referring to? ...Read more

Supposing radiation causes cancer, will that cancer be treated with more radiation?

Supposing radiation causes cancer, will that cancer be treated with more radiation?

Maybe: Sounds paradoxical, doesn't it? But it works. Radiation damages the genome and the mutations may eventually give rise to a cancer. Big doses simply cause cells of all kinds to die off, many cancers being vulnerable. The radiation-induced cancers are most often sarcomas or leukemias; a sarcoma may be palliated by a big dose of radiation (it's actually more toxic to fully-developed cancer cell. ...Read more

Describe breast cancer staging according tnm?

Describe breast cancer staging according tnm?

Tumor,Nodes,Mets: The t, n, m system classifies breast cancers based upon tumor size(t), lymph node status(n), and presence of cancer elsewhere in the body(m). Stage i is limited to small cancers +/- microscopic ln disease. Stage ii describes tumors 2-5cm +/- ln disease. Stage iii is for more advanced tumors (>5cm, skin/chest wall involvement) +/- multiple/distant ln. Stage IV describes metastatic disease. ...Read more

Stage iii-b colon cancer removed surgically. Suspected liver lesion resected and analyzed with not malignancy. Is kras analysis needed for recurrence?

Stage iii-b colon cancer removed surgically. Suspected liver lesion resected and analyzed with not malignancy. Is kras analysis needed for recurrence?

Possibly: For initial treatment after surgery, you shouldn't need to get kras testing. However, if this is metastatic or recurrent colon cancer, then it may help to determine if egfr based therapies like Cetuximab can help (they only work for kras "wild type"). Remember that if you do recur (god forbid), management may be different at that future time! not something to worry about with your current story. ...Read more

What is metastatic rectal cancer?

What is metastatic rectal cancer?

Tumor has spread: 'Metastatic' refers to a cancer that has spread to another site away from where it started. This happens when cancer invades blood vessels and lymphatics, allowing the cancer cells to spread and deposit in other organs. So ' metastatic rectal cancer ' means a tumor that started in the rectum is now outside the rectum, in other organs (liver is most common). ...Read more

Is colon cancer and olvarian cancer often related?

Is colon cancer and olvarian cancer often related?

No: Colon Cancer is induced for the most part in non hereditary disease by viral transfection. The most common organism is the polyoma virus. Ovarian cancer is not derived from this viral event. Colon cancer begins in the mucosa of the bowel where ovarian Ca is an epithelial disease similar to that of peritoneal carcinomatosis. The only relationship is when colon metastasizes to ovary. ...Read more

Are breast cancer and colon cancer linked?

Are breast cancer and colon cancer linked?

Not directly usually: There is debate about how closely these 2 cancers are related. Both have hereditary natures and are more common generally in obese patients. Both often begin with more benign precursor lesions like dcis for breast cancer and benign polyps for colon cancer. Both are very common but there is little evidence that having either predisposes to having the other. ...Read more

Need to ask question about cancer treatment. Had hysterectomy 9-26-11 pathology found cancer in the uterus muscle.  Oncologist stated treatment would include chemo and radiation although no further cancer was found after the CT scan.  What kinds of questi

I : I hope you have recovered from your surgery well. There are two main groups of uterine cancer that can involve the muscle. The more common type starts in the lining of the uterus and may grow into the muscle. This is called an endometrial carcinoma. The appropriate treatment for this after surgery will depend on how aggressive the cells look under the microscope, which is called the grade of the tumor as well as if there was any evidence of cancer outside the uterus. If this is what you have, you will most likely benefit from some sort of radiation which may include about 5-6 weeks of daily external radiation to the pelvic area and/or a few days of outpatient internal radiation to the vagina. Chemotherapy might be recommended as well if the cancer has spread outside the uterus or if the cells are high-grade. The other group of uterine cancers are tumors that actually started in the muscular wall of the uterus. These are called uterine sarcomas. There are multiple types of these tumors too and the appropriate post-operative treatment depends on the type of tumor and how far it has spread. This may consist of no further treatment, hormonal therapies, radiation or chemotherapy alone, or both in combination. You need to ask: 1) what kind of tumor you had. 2) what is the stage and what does this mean in terms of where the cancer was in your body. 3) what is the grade. 4) what treatment guidelines and data are being used to make the treatment recommendations. 5) what exactly the treatment will entail. 6) what are the expected short and long term side effects. 7) what benefit do are the treatments expected to give in terms of improving the cure rate. ...Read more

Diagnosed with liver cancer also breast cancer. What is the prognosis?

Diagnosed with liver cancer also breast cancer. What is the prognosis?

It is not very usual: To have two cancers at once' more likly the breast cancer is the cause of the liver lesion(s). Ifthere is doubt, a biopsy can be done to verify cell type and establish appropriate treatment, including presence of er/pr/her-2-neu - cell surface marker suggesting treatment. Liver metastasis can respond, but classically less responsive to hormones, and not having as favorable outcome to therapy. ...Read more

Stage 1 rectal cancer, removed April with clear margins. oncologist thinks a lung nodule may be inflammatIon as CEA normal. Could it be cancer?

You bet: Any patient with a lung nodule needs careful thoughtful evaluation. A normal CEA does not exclude possible malignancy. Hopefully this is something other than spread of cancer from the rectum, but you must be certain before it is no longer manageable. See a pulmonary expert. ...Read more
