1. A method for identifying a biomarker indicative of cervical precancer or cancer in a patient comprising generating an expression profile comprising measuring expression of at least three miRNAs in a cervical sample from a patient suspected of having a pre-cancerous or cancerous cervical condition
1. A method for identifying a biomarker indicative of cervical precancer or cancer in a patient comprising generating an expression profile comprising measuring expression of at least three miRNAs in a cervical sample from a patient suspected of having a pre-cancerous or cancerous cervical condition, wherein expression of hsa-miR-21 is measured using a nucleic acid probe comprising a sequence that is at least 95% identical or complementary to each of SEQ ID NO:183, expression of hsa-miR-143 is measured using a nucleic acid probe comprising a sequence that is at least 95% identical or complementary to each of SEQ ID NO:123, and expression of hsa-miR-218 is measured using a nucleic acid probe comprising a sequence that is at least 95% identical or complementary to each of SEQ ID NO:192, and identifying the patient as having biomarkers indicative of cervical precancer or cancer after measuring an increase in hsa-miR-21 expression and decreases in hsa-miR-143 and hsa-miR-218 expression compared to an expression profile of a normal cervical sample or a reference sample. 2. The method of claim 1, comprising measuring one or more miRNA that is hsa-miR-1 (SEQ ID NO:87), hsa-miR-224 (SEQ ID NO:199), hsa-miR-15b (SEQ ID NO:139), or hsa-miR-21* (SEQ ID NO:486). 3. The method of claim 1, wherein the patient is identified as having a biomarker indicative of cervical cancer based on measuring a increased expression of hsa-miR-21 in the patient's sample. 4. The method of claim 2, wherein the expression profile shows decreased expression of hsa-miR-1 or increased expression of hsa-miR-224, hsa-miR-15b, or hsa-miR-21* in the sample relative to the expression level of normal sample. 5. The method of claim 4, wherein decreased expression of hsa-miR-1 is measured in the sample relative to the normal sample. 6. The method of claim 1, wherein the sample from the patient is isolated RNA, fresh tissue or cells, frozen tissue or cells, fixed tissue or cells, or embedded tissue or cells. 7. The method of claim 1, wherein the cervical precancer is cervical squamous intraepithelial lesion or cervical intraepithelial neoplasia. 8. The method of claim 1, wherein the cervical cancer is cervical squamous cell carcinoma. 9. The method of claim 1, further comprising obtaining the cervical sample from the patient. 10. The method of claim 1, further comprising labeling miRNA from the cervical sample. 11. The method of claim 10, further comprising hybridizing the labeled miRNA to one or more miRNA probes. 12. The method of claim 1, wherein the expression profile of the one or more miRNA involves an amplification assay. 13. The method of claim 12, wherein the one or more miRNA is all or part of one or more of hsa-miR-1, hsa-miR-15b, hsa-miR-133a, hsa-miR-205, hsa-miR-21, hsa-miR-204, hsa-miR-195, hsa-miR-100, hsa-miR-99a, hsa-miR-368, hsa-miR-183, hsa-miR-224, hsa-miR-21* or combination thereof. 14. A method for identifying a biomarker indicative of cervical precancer or cancer in a patient comprising: a) measuring an expression profile of at least three miRNAs that includes has-miR-21 in a cervical sample from a patient suspected of having a pre-cancerous or cancerous cervical condition, wherein hybridization or amplification of miRNA is used to measure the expression profile, wherein expression of hsa-miR-21 is measured using a nucleic acid probe comprising a sequence that at least 95% identical or complementary to each of SEQ ID NO:183, expression of hsa-miR-143 is measured using a nucleic acid probe comprising a sequence that is at least 95% identical or complementary to each of SEQ ID NO:123, and expression of hsa-miR-218 is measured using a nucleic acid probe comprising a sequence that is at least 95% identical or complementary to each of SEQ ID NO:192, andb) identifying the patient as having biomarkers indicative of cervical precancer or cancer after measuring an increase in hsa-miR-21 expression and decreases in hsa-miR-143 and hsa-miR-218 expression compared to an expression profile of a normal cervical sample. 15. The method of claim 14, wherein the expression profile includes one or more of hsa-miR-1, hsa-miR-15b, hsa-miR-133a, hsa-miR-205, hsa-miR-204, hsa-miR-195, hsa-miR-100, hsa-miR-99a, hsa-miR-368, hsa-miR-183, hsa-miR-224, hsa-miR-21* or combination thereof. 16. The method of claim 14, wherein measuring the expression profile involves miRNA hybridization or amplification. 17. A method for identifying a biomarker indicative of cervical precancer or cancer in a patient comprising: a) measuring increased hsa-miR-21 and reduced hsa-miR-143 and hsa-miR-218 expression in a cervical sample from a patient suspected of having a pre-cancerous or cancerous cervical condition compared to an expression profile of a reference cervical sample, wherein expression of hsa-miR-21 is measured using a nucleic acid probe comprising a sequence that is at least 95% identical or complementary to each of SEQ ID NO:183, expression of hsa-miR-143 is measured using a nucleic acid probe comprising a sequence that is at least 95% identical or complementary to each of SEQ ID NO:123, and expression of hsa-miR-218 is measured using a nucleic acid probe comprising a sequence that is at least 95% identical or complementary to each of SEQ ID NO:192; andb) identifying the patient as having biomarkers indicative of cervical precancer or cancer. 18. The method of claim 17, wherein the expression profile includes one or more of hsa-miR-1, hsa-miR-15b, hsa-miR-133a, hsa-miR-205, hsa-miR-204, hsa-miR-195, hsa-miR-100, hsa-miR-99a, hsa-miR-368, hsa-miR-183, hsa-miR-224, hsa-miR-21* or combination thereof. 19. The method of claim 17, wherein measuring the expression profile involves miRNA amplification.
