What does it mean lymph nodes negative but 3 nodules found around the tumor , is it possible that other nodules might still be in the colon?

What does it mean lymph nodes negative but 3 nodules found around the tumor , is it possible that other nodules might still be in the colon?

Can't say for sure.: I am assuming you had a colon resection for cancer. It is encouraging that the lymph nodes were negative as that is an important prognostic factor in curing you. The 3 nodules around the tumor could be tumor in what were lymph nodes that have been totally replaced by tumor or could be satellite tumors. You should have had a colonoscopy to exclude other tumors in your colon. If not, you should. ...Read more

I am a 55 year old, post menopausal woman. My ER and pr are positive and her2 is negative. I have been diagnosed with stage t1n0m0 breast cancer, my tumor being 1.2 CM big. Can chemo be avoided?

I am a 55 year old, post menopausal woman. My ER and pr are positive and her2 is negative. I have been diagnosed with stage t1n0m0 breast cancer, my tumor being 1.2 CM big. Can chemo be avoided?

Need Oncotype-Dx: While your prognosis is excellent, we know that some women with your stage may benefit from traditional chemotherapy in addition to an aromatase inhibitor. Nowadays, we are moving towards molecular staging over anatomic staging; oncotype-dx is a multi-gene assay that can provide information regarding your probability of recurrence; if it is high, traditional chemo will be recommended. ...Read more

I : I suggest you make an appointment with the doctor who ordered the pet scan to review the images and adults with him or her. Ctac stands for "attenuation correction ct". This is ct, or computed tomography part of the combined pet/ct scan. It is what show the anatomy meaning all the organs and structures in the body. The 3.75 just means how thick the cat scan slices are. Unless a special kind of pet/ct dcan was done specifically to evaluate for a brain tumor, it is actually quite rare for brain tumors to show up on regular pet scans and they are usually not easily seen on the ct component of the scan alone, especially if no IV contrast dye aw given in addition to the pet scan sugar tracer. ...Read more

What does it mean to have a papilledemabrain tumor?

The skull is a finite space and if too much fluid builds up it leads to increases pressure. This can be seen by looking in the eyes and sometimes we see papilledema. Hope this helps. ...Read more

Can you tell me what 61 hounsfield units on a tumor means?

Can you tell me what 61 hounsfield units on a tumor means?

Refers to density: Hounsfield units are a measure of how easily xrays penetrate the object, and therefore how dense it is. For example structures with lots of air in them, allow xrays to easily pass and have very low hu values ( lung would be (-) 700, water is 0, muscle has a score of 40, bone being very dense is 700. What a score of 61 means depends on other factors ( where the tumor is, its shape etc). ...Read more
