Scalp cooling caps have become a useful tool to reduce hair loss during chemotherapy. However, there are specific situations where their use may not be appropriate, or even contraindicated. It is essential for patients to be aware of these cases in order to make informed decisions together with their medical team.
- Leukaemias and lymphomas
In the case of haematological cancers, such as leukaemias and lymphomas, the use of a cooling cap may not be recommended. Since these cancers circulate in the blood, there is a risk that by reducing blood flow to the scalp, chemotherapy drugs may not reach the scalp effectively, which could allow cancer cells to survive. - Metastases on the scalp
If there is evidence or suspicion that the cancer has spread to the scalp, the cooling cap is contraindicated. In these cases, cooling may decrease blood flow to the area, preventing chemotherapy drugs from adequately reaching the cancer cells present. - Cancers of the central nervous system
For patients with central nervous system (CNS) cancers, such as certain types of brain tumours, there is concern that the use of the cooling cap may interfere with treatment. Although there is no absolute consensus, some oncologists prefer to avoid the use of caps in these cases to ensure that treatment adequately reaches all necessary areas. - High-dose chemotherapy treatments
In chemotherapy treatments involving very high doses of drugs, the cooling cap may not be appropriate. The aggressiveness of this type of chemotherapy requires that the drugs circulate unimpeded throughout the body, and some oncologists feel that cooling may interfere with the full distribution of the treatment. - Cold sensitivity and patient comfort
In addition to medical reasons, some patients may find the sensation of cold too uncomfortable or intolerable. Although it is not a medical contraindication, it is important to consider the patient's comfort during this process.
What should I do if I am in doubt about the use of the cooling cap?
It is crucial that you talk to your oncologist before making any decisions about the use of a cooling cap. Each type of cancer and chemotherapy treatment is different, and your doctor will be able to guide you as to whether this option is appropriate in your particular case.
Conclusion:
The scalp cooling cap can be an effective option to prevent hair loss in many chemotherapy treatments. However, in cases such as leukaemias, lymphomas, scalp metastases, central nervous system tumours or high-dose chemotherapies, its use may be contraindicated. The best way to decide if the cap is right for you is to consult your medical team, who will assess your particular case.
