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

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

Can breast cancer recur after radiation therapy?

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

Could exposure to ionizing radiation progress pkd?

Pkd and ionizing rad: Data are not clear on this. For sure, select mutations on either chromosome 16 or chromosome 4 lead to PKD expression. Scientists have long thought that a single mutation that affects polycystin expression leads to cyst formations. Newer data show that second or third or fourth mutations on these chromosomes affect expression of pkd. So, it is conceivable that yes ionizing rad could affect pkd ...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
