Claims4
A method of diagnosing cancer in a patient, comprising
- (a) measuring the level of isotope 36S in a blood sample or a tissue sample of the patient using a double-focus type mass spectrophotometer;
- (b) measuring the level of at least one of the calcium isotopes 42Ca, 43Ca, 44Ca, 46Ca and 48Ca in a blood sample or a tissue sample of the patient using a double-focus type mass spectrophotometer;
- (c) diagnosing cancer in the patient if (i) 36S is not detected
- and (ii) the level of the at least one calcium isotope is greater than the level of a normal standard for the at least one calcium isotope.
