The invention relates to a hyperthermia (focused ultrasound—FUS) method where an energy source is applied, repeatedly, to a desired part of the body to induce hyperthermia, e.g. using image guidance. Hyperthermia is applied after a drug or biopharmaceutical (API) and/or their labelled equivalents (theranostics) and/or their drug delivery systems has been administered to the live subject to cause the enhanced tissue distribution and/or controlled release of the drug, previously encapsulated in thermo-sensitive (lipid nano)particles, to a desired site of the body. Hyperthermia (Ultrasound) is then halted, and the site of interest. Hyperthermia is then applied again using image guidance to monitor drugs accumulation in the tissue. The drug and or the drug delivery system are also labelled (for imaging) to allow real time monitoring and modulation of the API in the human body which can be used to direct and guide the FUS at the site of interest.
