MOHS Surgery: Mohs surgery has come to be accepted as the single most effective technique for removing basal cell carcinoma and squamous cell carcinoma (bccs and sccs), the two most common skin cancers. It accomplishes the nifty trick of sparing the greatest amount of healthy tissue while also most completely expunging cancer cells; cure rates for bcc and scc are an unparalleled 98 percent or higher. ...Read more

Biopsy: "sigmoid colon, well differentiated adenocarcinoma, grade i" does this indicate that the tumor won't probably metastasize? Triphasic CT shows a lesion in the liver (1cm) as well.

Biopsy: "sigmoid colon, well differentiated adenocarcinoma, grade i" does this indicate that the tumor won't probably metastasize? Triphasic CT shows a lesion in the liver (1cm) as well.

Grade 1 is a good: Sign, but nothing is guaranteed. Need to further understand the liver lesion as well. Work with the medical team to put together the best treatment plan for the individual patient situation. ...Read more

What are hypometabolic tumors mean on pet/ct scan?

What are hypometabolic tumors mean on pet/ct scan?

Increased metabolic activity is a common feature of cancer as well as Inflammation. If there is no increased uptake of PET material(that means it is hypometabolic, as opposed to hypermetabolic, the lesion/tumor is unlikely to be Cancer(with a few exe ...Read more

I just had a CT scan of my head will this find all tumors?

I just had a CT scan of my head will this find all tumors?

Not ALL....: No ct scan (or mri, which is better for this) can detect everything. The results of any scan have to be put in the context of the symptoms that led to it being ordered. You doc will go over its findings with you and decide if you need additional tests. That being said, a good ct with contrast should see a good percentage of brain lesions. Best to you. ...Read more

Possible for a 6.6mm tumor to not show up on X-ray or CT scan?

A cm is: Roughly a half-inch, so 6.6 is a little more than half that and quite easy to not been seen on ct, and unlikely to be seen on a plain film...And I am speaking of chest. Abdomen or pelvis even easier to miss. ...Read more

Are smaller sized tumors the only ones a CT scan will miss? How serious are small ones? Do small ones cause symptoms, if so what?

Few things: I think you may have asked part of this before. Ct can miss small tumors. Seriousness depends on what they are. Small ones can cause many different symptoms. Depends on where they are in the brain. ...Read more

Ct scan, said 10mm stone had lipo, xray not sure if its gone. Is it obvi on CT scan stone vs tumor? Uncert results making me nervous

CT is better: Bobcat: a ct scan is better than a regular xray to see smaller stones. The problem comes in when you already had a ct because we don't want to continuously expose you to the radiation of a ct scan. A sonogram might be a good option for you because it will show the kidney and whether there is any obstruction caused by the stone. ...Read more

Ct Scan (Definition)

Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...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
