Ct neck shows scattered subcm short axis dimension lymph nodes anterior posterior cervical chains bilat. 2 x triple neg breast cancer surv. Biopsy?

Imaging/biopsy: You have been through a lot. Imaging with ct scan provides information and helps guide next steps, but is not diagnostic. A biopsy obtains tissue for pathology to make the diagnose of lymph node. The timing of biopsy in relation to your overall health will be best addressed between you and your doc. Take family or friend with you.

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

Does breast cancer show up in blood tests?

Does breast cancer show up in blood tests?

Not really.: Apart from tests for genetic markers, breast cancer is usually diagnosed from self exam or mammography where a mass is detected. If it persists throughout the cycle, or is in postmenopausal women, it should be aspirated. If the fluid is bloody or leaves a residual mass, or the original mass is solid, a mammogram and excisional biopsy are done.

What are the necessary blood tests after treatment of breast cancer to detect if your ok. Is ca 125 important?

No: Ca-125 not important for breast cancer. Good test for ovarian cancer. The most important things are routine physical exam. Most recurrences are found by the patient or the physician. Hope this helps. No routine blood tests have been shown to be of benefit. However, if someone received chemotherapy, I typically check blood because they received chemo.

Could breast cancer show up on a blood test?

Could breast cancer show up on a blood test?

No: Breast cancer does not show up on a blood test. Breast cancer is diagnosed by biopsy of abnormal breast lesions seen on mammogram or biopsy of a breast lump.

Is it possible for breast cancer to show up on a blood test?

Is it possible for breast cancer to show up on a blood test?

No: As of today, all blood tests looking for tumor markers, that is molecules representing the tumor, that are shed into the blood stream are carbohydrate in origin. Ie. Ca 125, ca 19.9 are markers with the ca prefix represent carbohydrate antibody, such markers are seen in many tumors and many cases of organ inflammation. As such they can only be used for monitoring.

After finding a breast lump, I had a blood test that came back normal. Is it still possible to have breast cancer?

After finding a breast lump, I had a blood test that came back normal. Is it still possible to have breast cancer?

Yes! Yes! Yes!: There is not a blood test to detect breast cancer. If there is an abnormal lump, you need a mammogram and ultrasound and then a biopsy to make a diagnosis. Only a biopsy, which is taking a sample of the lump, can determine if you do or do not have breast cancer. A biopsy can be done with a needle and results obtained in 24-72hours. See a breast specialist for evaluation-do not delay!

I am a breast cancer survival - do I need to do the tumour markers blood test -ca153, ca19.9, ca12.5, cea, afp?

I am a breast cancer survival - do I need to do the tumour markers blood test -ca153, ca19.9, ca12.5, cea, afp?

Generally no: Standards of care in the us do not recommend routine tumor marker testing in cancer survivors (we usually do ca 27.29 for breast cancer). Markers are mostly useful to assess response to therapy in patients with advanced cancer. That said, many oncologists (myself included) will sometimes order routine markers in cancer survivors depending on the circumstances.

After finding a breast lump, I had a blood test that came back with normal blood count, is it still a possibility to have breast cancer?

After finding a breast lump, I had a blood test that came back with normal blood count, is it still a possibility to have breast cancer?

Blood tests don't he: No blood tests would help to diagnose breast cancer. The only way to diagnose cancer is biopsy of the lump once it is confirmed to be real on an x-ray (mammogram). So you are advised to find a doctor who knows how to investigate a lump in breast, which most dcotors do. But a physical exam is the first step in order to decide if an x-ray or ultrasound is needed. Any palpable lump requires biopsy.

I'm stage 4 Breast cancer. Been having pain in ribs/ shoulder for 2 mths. Also cancer antigen 27. 29 blood test is back above normal. Is cancer back?

I'm stage 4 Breast cancer. Been having pain in ribs/ shoulder for 2 mths. Also cancer antigen 27. 29 blood test is back above normal. Is cancer back?

See your oncologist.: Stage IV describes invasive breast cancer that has spread beyond the breast and nearby lymph nodes to other organs of the body, such as the lungs, distant lymph nodes, skin, bones, liver, or brain. Talk to your oncologist to determine the extent/ or remission of the cancer. Stage 4 usually means that cancer was not just in the breast area.

Just had my 4th blood test for elevated AST & ALT since 3/13. Alt 101. Ast 58. 3 yrs from breast cancer &on tamoxifen. Shd I be getting some tests?

Hard to tell: ..With the info provided. Are they high but stable or are they progressively going up? What other meds you take? Any concerning symptom? In a way, you are getting tests, your doc has opted to follow up your lfts periodically. I think you need to voice your concerns to him/her so that he/she goes over this and the future plan of attack. Best to you.

Is it common for people who are using herceptin (trastuzumab) as a breast cancer treatment to have raised liver blood test readings?

Is it common for people who are using herceptin (trastuzumab) as a breast cancer treatment to have raised liver blood test readings?

Not usually: Herceptin (trastuzumab) is a pretty safe drug. As far as I know it does not affect liver functions. But many other drugs including chemotherapy can increase the liver enzymes. You should ask you oncologist to confirm it with the drug manufacturer or from a drug information source.

36 year-old woman whose mother was diagnosed with breast cancer at age 34 and a PALB2 mutation wonders if mastectomy is needed to lower her risk.....?

36 year-old woman whose mother was diagnosed with breast cancer at age 34 and a PALB2 mutation wonders if mastectomy is needed to lower her risk.....?

No!: Although the PALB2 mutation increases risk, preventive mastectomy is not recommended. There are other ways to decrease your risk including taking raloxifene or tamoxifen. See a medical oncologist to discuss this (and a genetic counselor!)

Could doctors detect breast cancer through blood?

Possible but...: ...Unlikely. If the breast cancer spread to the liver or the bones, you may sometimes see elevations of certain enzymes or calcium levels. Also, if for reasons unexplained, a patient gets a ca27.29 (aka tumor marker) drawn, it may be elevated if there is cancer. Please understand that bloodwork, especially the ca27.29, is not a proper screening for breast cancer.

How to boost white blood counts during chemotherapy for breast cancer?

Growth factors: If your blood counts are severely low then use of growth factor injections (neulasta (pegfilgrastim) or neupogen) can help boost the recovery of your blood counts after chemotherapy.

Often curable if found early and treated effectively with surgery, hormonal therapy, chemotherapy and targeted therapy, or a combination thereof. Early detection before the malignancy becomes large enough to be felt depends on mammography/sonography and MRI imaging of the breast ...Read more
