DCIS, left breast, biopsy itself removed high grade cancer cells, lumpectomy path 100% cancer free. Radiation necessary? What about proton therapy?

DCIS, left breast, biopsy itself removed high grade cancer cells, lumpectomy path 100% cancer free. Radiation necessary? What about proton therapy?

It depends: It may depend on your age. Radiotherapy to your involved breast may be required as it is the standard of care. Ask your doctor and let us know what advice you receive. Tamoxifen is another medication recommended after completion of Radiotherapy. ...Read more

Mammogram (Definition)

A mammogram is the "gold standard" screening test for breast cancer. It's well established that yearly 'grams will DX cancers well before they are palpable, leading to earlier diagnoses and saved lives. All experts agree to begin yearly mammograms by age 50; many (including myself) believe the pro's outweigh the con's to begin at 40. Regrettably, less than half of all women ...Read more

Mammogram, ct, MRI and ultrasound tests for breast cancer - what is best?

Mammogram, ct, MRI and ultrasound tests for breast cancer - what is best?

Situational: For screening: mammograms are the most valuable. For diagnosis (palpable mass, mammographic density): ultrasound can be very helpful. Mris are the most sensitive test for breast cancer, but their prohibitive cost makes this unaffordable for large-population screening. It is best used in high-risk patients, those with very dense breast tissue, and for evaluating the extent of a known breast cancer. ...Read more

Tsh level 5.58, no symptoms, u/s found 1cm subtle hypoechoic nodule w/increased peripheral vascularity. Pcp ordered rai uptake scan before fna. Why?

Tsh level 5.58, no symptoms, u/s found 1cm subtle hypoechoic nodule w/increased peripheral vascularity.  Pcp ordered rai uptake scan before fna.  Why?

I have no idea: Hi. It's not a hyperactive nodule...we know that from the TSH. I'd go straight to an FNA. The scan will show a "cold" nodule, which we already know it is, and will not help differentiate benign from cancer. FNA cytology (hopefully with gene testing) is all you need at this point. Good luck. ...Read more

Rise in psa after radiation and hormone treatment?

Not enough info: You describe a complex situation that requires complete review of the medical record. Questions that need to be answered include: - cancer grade - psa at diagnosis - rate of psa rise - stage, ?Mets? - duration of hormones - how long since radiation... See your urologist or radiation oncologist and ask them all of your questions. If you don't feel comfortable with them, seek another opinion. ...Read more

Stage 2B idc breast cancer, triple positive. Us shows 6mm thyroid nodule with calcifications next to carotid. Should i insist on fine needle biopsy?

Stage 2B idc breast cancer, triple positive. Us shows 6mm thyroid nodule with calcifications next to carotid. Should i insist on fine needle biopsy?

Depends: This condition is unrelated to your breast cancer history. Ask your doctor what concerns or not are registered by the radiologists. Some type of thyroid calcifications are more likely to be benign. 6mm thyroid nodule is small & need to know risks of trying biopsy near carotid artery too. The doctor who ordered the study would know much more to help you than is able to be reported here. ...Read more

Cea blood test levels low but cat scans show more cancer?

Cea blood test levels low but cat scans show more cancer?

Possible: Please note that cea is just another tool we have and as such it is not perfect. Many patients have elevated cea and have no cancer and many others have clinical and x-ray evidence of active cancer and yet their cea is normal. Such tumors just don't produce cea and in those cases, the test is useless. No test is infallible. ...Read more

DCIS calcifications ,biopsy itself removed all bad cells, lumpectomy pathology that followed 100% cancer free, radiation to aggressive?44 yr old.

DCIS calcifications ,biopsy itself removed all bad cells, lumpectomy pathology that followed  100%  cancer free, radiation to aggressive?44 yr old.

Depends: Two important other pieces of information are what the "grade" of the DCIS was which implies how aggressive it might be, and how much normal tissue was between the edge of what was removed and the DCIS. Both of these are taken into consideration when evaluating the role of radiation therapy for DCIS. Talk to your oncologist, your surgeon, and your radiation oncologist for more details. ...Read more

On a pet scan does a lower SUV uptake meAn less aggressive cancer ? The SUV uptake was 5.2,

On a pet scan does a lower SUV uptake meAn less aggressive cancer ? The SUV uptake was 5.2,

No: SUV has no bearing on the aggressiveness of the cancer. It is a relative measure of the glucose metabolism. In fact, some very aggressive tumors have no FDG uptake at all. Some benign conditions like infection can have high uptake. The standard uptake value depends on many factors like patient body size and serum glucose level and the normal uptake in the tissue surrounding the target lesion. ...Read more

1st mammogram ever and abnormal, family history breast cancer. Single group amorphous microcalcs in left breast. US BIRAD 3 and now going for MRI. Biopsy?

1st mammogram ever and abnormal, family history breast cancer. Single group amorphous microcalcs in left breast. US BIRAD 3 and now going for MRI. Biopsy?

A grouping: of amorphous calcifications is probably not appropriate for BIRAD category 3(probably benign). Although they are still likely going to be benign, stereotactic needle biopsy may be more appropriate management, and BIRAD 4 a more appropriate category. Breast MRI is generally not that useful in the imaging work up of microcalcifications. ...Read more

Questions: http://www.jbc.org/content/28/1/237.full.pdf to better understand that urinary calcium levels vary. It is best to do a creatinine clearance and a 24 hour urinary calcium level. Whoever ordered it should review it with you. The thyroid function is ok so you should stay on that dose. The bone density is more accurate in hips and lumbar spine and should be reviewed with your doc. ...Read more

Is breast density a risk factor for breast cancer? Mammogram noted "extremely dense breasts".

Is breast density a risk factor for breast cancer? Mammogram noted "extremely dense breasts".

Yes, breast density: is a risk factor for breast cancer. The relative risk for extremely dense breasts is about 4x the relative risk of patients with almost entirely fatty breasts, and about 1.6x the RR for "average" density breasts.

32 yo, breast cancer stage 1b, double mastectomy, micrometastasis in one lymph node. TCH treatment, followed by radiation. Prognosis thoughts????

32 yo, breast cancer stage 1b, double mastectomy, micrometastasis in one lymph node.  TCH treatment, followed by radiation. Prognosis thoughts????

Prognosis is good!: I would need more information to be definitive but with a small primary tumor (stage 1) and only micrometastasis in one node, your prognosis should be relatively good. Since you received TCH, it is obvious that you had her2 positive breast cancer so your prognosis is less favorable than had her2 not been positive. However, 5 year survival in excess of 85% is shown in recent studies with TCH. ...Read more

Had VIP chemo for stage 3 testicular, hCG at 43 tumors are smaller. Pet scan no intense hits. Alphaf normal. Cause for hCG levels higher?

Had VIP chemo for stage 3 testicular, hCG at 43 tumors are smaller. Pet scan no intense hits. Alphaf normal. Cause for hCG levels higher?

Not an easy situatio: It is hard to assess your complex situation through few lines, but VIP is usually given as a second line chemotherapy for testicular cancer mostly in the salvage setting. Persistent tumor marker is usually a sign of persistent disease and you need a thorough. Evaluation by a GU medical oncologist and preferably in a multidisciplinary setting ...Read more
