In brief: Many cancers
Many cancers in many organs won't show up in blood work.
Kidney, bladder, bowel, skin bone etc can all be present with all blood tests being normal. Lyphoma is lesslikely, but blood test could be normal early on.

In brief: Yup
Some skin cancers won't show up in the bloodwork; unless they have advanced so far as to spread to other body systems(metastasize) lymphoma would normally present with a very high sed rate(esr) and possibly some abnormalities in a complete blood count(cbc).
If you are concerned about this then please see your primary care doc for an evaluation.

In brief: Yes
Not all cancers including lymphoma are associated with abnormalities detectable by routine blood testing.
In other words, a normal blood result does not rule out cancer. The most common cancer identifiable by routine blood testing is leukemia.

In brief: No
Most cancers will not show up unless the end organ they damage show laboratory changes.
But leukemias and blood cell cancers will show up as the cancer affectes the cel pproduction in reg blood abnormal liver function tests may indicate a problem but usually cancer markers are not used for diagnosis, but lab tests indicate a need to investigate the abnormality which many time leads to diagnosis.

In brief: Cancer blood tests
There are virtually no routine blood tests that do detect cancer. The psa blood test for prostate cancer is the best known.
Other common tests are the cea for colon cancer and ca125 for ovarian cancer, but these are not useful for diagnosis, but rather for following patients who have disease. For patients with hepatitis c tests like AFP and HCG are used watch for the development of liver cancer.

Exceptions include leukemias, but generally blood tests are not specific for cancer. As noted "tumor markers" are (may?) be useful for tracking treatment or recurrence, but are generally not diagnostic.
