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.
Yes. Yes it does, but you have to specifically order the correct tumor marker and not all breast cancers have elevated blood levels of tumor markers. This means that it is not a good way to monitor for breast cancer.

I went for blood tests today to check tumour markers as I have previous breast cancer history. I ould only get 2 tubes of blood but needed 4. I am also going for a bone scan. Opinions?

Might be enough. The requirement for number of tube comes from both the type of tube needed for a particular test as well as the volume of blood needed. The volume part also depends on how concentrated your blood is--less liquid in your blood means you need more tubes. Your doctor will be notified if some of the tests needed could not be done, and then he or she can decide if you need to be drawn again. Read more...
No problem. In all likelihood, this should not be an issue. Tumor markers are generally not recommended for patients with a history of breast cancer, primarily because the markers that we have are quite poor. They tend to be most helpful when tumors are advanced and when patients are undergoing chemotherapy. If the tumor markers go down, this is often taken as a sign that the therapy may be working.

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! Read more...
Yes. Blood tests tell almost nothing about whether or not you have breast cancer. Blood tests can only give us informatin about your overall health such as your blood cell counts and your liver and kidney function. A breast lump should be evaluated with a mammogram, a breast ultrasound, a breast mri, a breast biopsy, or some combination of the above. Read more...

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. Read more...
