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. ...Read more

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

Can cancer always show up in blood tests?

Not all cancers: Most cancers are not detected in the blood initially. There are a few that produce markers that allow us to screen patients for cancer with a blood test. Prostate cancer is the most common. There are some blood markers that are used to detect GI cancers as well as to follow patients with gyn cancers as well as breast. Testicular cancer also has commonly used markers. Must be in context of case. ...Read more

Very.....: Despite the preachings of the american cancer society, and their slogan...."the cure is just around the corner, " not a lot of advances have been made in cancer treatment in the past 30 years. Sure, certain limited types of cancer have better survival rates, but most do not. Oncologists are still infusing the same "rocket fuel" they did 30 yrs. Ago, with poor results. Take your above dx.

Can xrays and blood tests show or detect cancer? Can xrays and blood tests show cancer? What are the best ways to detect cancer?

It : It depends what kind of cancer. There are some types of cancer that can be detected by special blood tests, although many of these tests can be abnormal in other conditions too and they are mostly used to check up on people who already are diagnosed cancer in whom the doctor knows that the blood test is abnormal because of the cancer. Mammography is now the only proven x-ray study for screening people without cancer in order to find a new cancer (breast) early. However, there are studies being done to see if ct scans can help diagnose more early lung cancers in people at high-risk like heavy smokers. Other than mammography, most imaging studies are used only when someone has some sort of suspicious symptom or other finding in order to determine if a tumor is the cause of the problem. They are also used for "staging" after a cancer has been diagnosed which means to look to see where the cancer might have spread. Finally, imaging tests might be used to follow how well a treatment is working or to look for a recurrence after treatment has stopped. The problem with imaging studies is that most of them can only find a tumor that is a few millimeters in size. This is already hundreds of millions of cancer cells. You need to talk to your doctor about cancer screening. She or he can discuss the appropriate screening tests for you which depend on your age, gender, environmental exposures, and family history. These may include things like a psa test and rectal exam for prostate cancer, mammography or other images for breast cancer, a blood test and pelvic exam for uterine cancer, a pap smear for cervical cancer, a stool test and/or colonoscopy for colon cancer, or others. ...Read more

Would blood tests show cancerous tumors, or even benign one's in the body? OR Would a regular blood test show indications of cancer / a tumor inside?

Would blood tests show cancerous tumors, or even benign one's in the body? OR Would a regular blood test show indications of cancer / a tumor inside?

Not very helpful: We don't have reliable blood tests to look for the common cancers. Your best bet is cancer surveillance (in your case, I trust you get pap smears if you have ever had someone special), and know the usual warning signs and get seen if they come up. ...Read more

Do blood tests/CT scans show if you have cancer in the results?

Do blood tests/CT scans show if you have cancer in the results?

Yes, most times it d: Cancer is not difficult to diagnose but you need to go to an experienced doctor/preferably an oncologist. We look for any abnormal growth in the common sites affected by cancer(such as Lungs, Colon, Breast and Prostate). Blood tests are an aid but only provide indirect support for diagnosis. There is no single blood test that wil reliably show Cancer, at least not yet, but someday soon it is likel ...Read more
