Can my mother continue on Folfox7 treatment even if she has thrombocytopenia?

One side effect of the FOLFOX treatment is a decrease in the number of platelets in your body (thrombocytopenia), making bruises easy to develop and hard to heal. This is because the chemotherapy drugs in this treatment, while stopping the growth of cancer, also stops the bone marrow from making new platelets. So most likely, your mother has thrombocytopenia BECAUSE of the FOLFOX treatment. Thrombocytopenia is an expected side effect of FOLFOX.

When thrombocytopenia is severe (less than 10,000 platelets/ul), the doctor might decide to lower the dose of the FOLFOX drugs, or delay the treatment. However, this would decrease the patient's chances of surviving the cancer.

One way for a patient with thrombocytopenia to continue the FOLFOX treatment is to give the patient platelet transfusions (add platelets into the patient's body). And if the thrombocytopenia is severe, the doctor may want to keep the patient in the hospital for the patient's safety (this is because the patient will be easily bruised, and will bleed excessively, so staying in the hospital during the treatment would be best for the patient).

I agree with the above answer, but ultimately, this is a question for the doctor. While chemotherapy can help us beat cancer, it's not very pleasant for the patient. Hopefully one day, we'll find an even more effective drug, with less of these side effects. Talk to her doctor, since that is the person who is the expert of this situation.
